Max Planck Institute for Chemical Physics of Solids

Max Planck Institute for Chemical Physics of Solids

The Max Planck Institute for Chemical Physics of Solids is dedicated to the discovery of new materials with unusual properties. To this end, researchers must have a fundamental understanding of the interrelations between the atomic structure, chemical bonding, electron states and the properties of a compound. The key research focus of the Institute is compounds of different metals. Chemists and physicists as well as experimental and theoretical scientists use state-of-the-art instruments and methods to investigate how the chemical composition, configuration of atoms and external forces affect the behaviour of electrons. It is these that are responsible for the magnetic, electronic and chemical properties of the compounds, and thus for their potential use as materials.

It is frequently only the development of new materials that makes technological advances possible, whether in the areas of energy supply or information technology. With the Heusler compounds, Claudia Felser, Director at the Max Planck Institute for Chemical Physics of Solids in Dresden, uncovered a rich source of materials that offer promising properties for a variety of applications.

Electric cables that routinely conduct electricity without loss – physicists have been motivated by this idea ever since superconductivity was discovered 100 years ago.

Electricity from Hot Air

MPR 1 /2011 Materials & Technology
Even the most efficient motor generates more heat than propulsion. However, thermoelectric generators could convert some of this unused energy into electricity. Scientists are currently searching for suitable materials.
They are called otoconia – tiny crystals in the inner ear that help us maintain our balance. A good reason to take a closer look at these particles.

Covalence and ionicity in compounds of MgAgAs-type: from concepts to structure prediction

2017 Wagner, Frank R.; Bende, David; Grin, Yuri
Chemistry Material Sciences Particle Physics Plasma Physics Quantum Physics Solid State Research
Analysis of chemical bonding in compounds of the MgAgAs type of structure by bonding indicators in position space resulted in a generalization of the 8­–N rule for bonds of variable polarity. Position-space indicators enable quantification of ionicity and covalence, which was successfully used to explain the different site preference in main-group and transition-metal compounds of the MgAgAs type. On this basis, it was possible to propose promising candidates for new compounds with the MgAgAs structure type, which was subsequently verified for the majority of compounds by laboratory synthesis. more

Topological Weyl semimetals

2016 Yan, Binghai; Felser, Claudia
Chemistry Quantum Physics Solid State Research
In recent years, theoretical physicists discovered that the topology of a material can lead to interesting new quantum properties. This simple concept can be applied to the electronic structure of semiconducting materials in which relativistic effects are important. In 2015, several materials like NbP, NbAs, TaP, TaAs, und MoTe2 have been suggested by theoreticians as promissing, so-called Weyl semimetals, and have been physically characterized just a bit later. The special feature is that Weyl fermions, which occur in these materials as quasiparticles, exist in two chiralities. more

Hunting for the electrical properties of topological insulators

2015 Höfer, Katharina; Becker, Christoph; Rata, Diana; Swanson, Jesse; Thalmeier, Peter; Tjeng, Liu Hao
Chemistry Solid State Research
Topological insulators form a novel state of matter that open up new opportunities to create unique quantum particles. Many exciting experiments have been proposed by theory, but still await their experimental verification, not to mention their implementation into applications. The main obstacle is the extrinsic conductivity associated with the unavoidable presence of defects in their bulk, as well as impurities on their surfaces. For Bi2Te3 films it is possible to obtain the desired quality by carrying out the preparation and characterization entirely under ultra-high vacuum conditions. more

A knowledge-based concept has proven as efficient strategy for the development of innovative catalysts. Understanding of the crystal structure and the atomic interactions within intermetallic compounds allows for selection of suitable intermetallic compounds as effective hydrogenation catalysts. In contrast to the widely applied trial-and-error approach, the knowledge-based approach is an advantageous alternative, demonstrating the application potential of intermetallic compounds in heterogeneous catalysis.

A ferromagnetic transition at an extremely low temperature of only 0.15 K (−273°C) has been discovered in the compound YbNi4P2. The properties of this phase transition contradict current theoretical predictions and evidence the existence of a ferromagnetic quantum critical point (QCP). The existence of such a QCP has been a matter of discussion as long as 40 years ago, but had been dismissed in the past 15. The search for and the investigation of QCPs is not only a central subject of modern fundamental research, but is also relevant in the development of new technical applications.

Chemistry Material Sciences Particle Physics Quantum Physics Solid State Research

Topological insulators (TIs) are a new quantum state of matter, which have attracted interest of condensed matter science. The materials are small band gap insulators with robust gapless surface states. Remarkable is that topological insulators can be predicted by ab initio theory and even understood from a chemist’s perspective. Herein, a simple recipe based on bonds, bands, symmetry, and nuclear charge will be given to motivate a systematic search for new topologically nontrivial materials.

Quantum criticality is currently pursued across many areas of correlated matter. A particular focus is on quantum criticality in itinerant electron systems. It has been shown that the traditional theory of metals breaks down in the vicinity of a novel class of quantum critical points in metals. A better understanding of the physics of these novel quantum states yields new insights into the occurence of magnetism and superconductivity. more

Sr3[Co(CN)3] and Ba3[Co(CN)3]: "Simple" compounds with extensive consequences on the chemistry of highly reduced metalates

2012 Höhn, Peter; Jach, Franziska; Karabiyik, Boris; Agrestini, Stefano; Wagner, Frank-R.; Ruck, Michael; Tjeng, Liu Hao; Kniep, Rüdiger
Material Sciences Solid State Research
The CN ligands in the isotypic compounds Sr3[Co(CN)3] und Ba3[Co(CN)3] have lost their "innocence" by higher reduction and weakening of the C–N bond, for the first time. For cobalt a closed-shell (d10)-configuration was determined. The resulting mesomeric structures of the trigonal-planar complex anions, [Co1–(CN)2(CN)3–]6–, open new insight into the chemistry of metalates and coordination compounds of transition metals with CN ligands. Finally, consequences on the chemistry of carbonylmetalates can be expected, too. more

Zero resistance by magnetism

2012 Stockert, Oliver; Arndt, Julia; Jeevan, Hirale S.; Geibel, Christoph; Steglich, Frank
Solid State Research
The question about the origin of unconventional superconductivity is one of the central issues in current condensed matter physics. Within an international collaboration scientists from the Max Planck Institute for Chemical Physics of Solids discovered that magnetic interactions are responsible for the Cooper pair formation and hence for the lossless current transport. While in conventional superconductors magnetism is detrimental for superconductivity, magnetism is an essential prerequisite for superconductivity in materials displaying unconventional superconductivity. more

The interaction of structure and magnetism of intermetallic compounds depends on the local as well as on the periodic assembly of the atoms. In order to understand the contribution of the local properties investigations by means of appropriate methods are necessary. Nuclear magnetic resonance (NMR) spectroscopy seams to by highly suited for this task. more

New phenomena in strongly correlated electron systems

2008 Wirth, Steffen; Singh, Surjeet; Capan, Cigdem (Louisiana State University, Baton Rouge, USA); Nicklas, Michael; DiTusa, John F. (Louisiana State University, Baton Rouge, USA); Fisk, Zachary (University of California, Irvine, USA); Steglich, Frank
Strong electronic correlations in solids may result in fascinating, yet often not fully understood phenomena. The latter include unconventional superconductivity and quantum criticality in heavy fermion metals. Here, magnetotransport measurements may shed light on the impact of antiferromagnetic spin fluctuations on these phenomena. Nonetheless, further detailed experimental and theoretical investigations are required for a more complete comprehension within this emerging field of solid state physics. more

Complex metallic alloy phases are intermetallic compounds with prominent features compared to simple metallic systems. They are based on giant unit cells comprising up to more than thousands atoms per cell, hierarchical structures and inherent disorder phenomena. The characteristic features originate from a cluster substructure, which controls short and long range order as well as the physical properties. more

For deeper insight into this behaviour a compound with the same crystal structure type from the chemical system Zr–As–Se was studied extensively in terms of chemical composition, crystal structure and electrical resistivity at low temperatures. The results indicate the unusual behaviour of ZrAs1.4Se0.5 to be connected with dynamical phenomena within the anionic substructure. more

Quantumphenomena and Superconductivity

Quantum Physics Solid State Research
All developments achieved to date in the fields of medical-, information- and sensor- technology are based on models which are well established in physics and chemistry and which reflect the state of knowledge of fundamental research until the middle of the last century. Further progress, however, seems to be possible only if we learn to understand a new state of condensed matter, which can not be described within the context of the established models. This new state is dominated by quantum phenomena. Quantum phenomena come into play, when spatial dimensions become smaller than the wavelength of light (nano-technology) or when extremely strong correlations build up among the electrons of the solid (Quantum Hall Effect, Collossal Magnetoresistance, High Temperature Superconductivity (HTSC)). Here we report two outstanding discoveries which could be particularly important for the understanding of the HTSC. At the heart of the description of HTSC lies the assumption that superconductivity is created by coupling the charge carriers via magnetic fluctuations. In CeCu2Si2, a compound whose properties are related to those of HTSC, we not only have found hints towards the existence of a magnetic coupling mechanism but furthermore, for the first time, have been able to collect evidence for the existence of an additional, completely new coupling mechanism. The second discovery concerns the physical properties of a strongly correlated electron system (YbRh2Si2) in the vicinity of the magnetic quantum critical point. In YbRh2Si2 the strongly interacting charge carriers can not be treated within the concept of weakly interacting heavy quasi particles, as it is successfully done in heavy electron metals away from quantum criticality. In contrast to hitherto models, the quasiparticles in YbRh2Si2 seem to disintegrate into a charge part (current) and a spin part (magnetism) when approaching the quantum critical point. more
