The electronics of the future could operate with light instead of electricity – or a combination of the two. As yet, no ideal light sources are available for this, however, nor are fibre optics fully developed. The development of such materials is one of the challenges that the scientists at the Max Planck Institute for Microstructure Physics in Halle have taken on. They investigate how the microstructure and nanostructure of metallic compounds affect their physical properties, for example how they behave as fibre optics or their magnetic characteristics. Their research concentrates on materials in low dimensions, for instance in a two-dimensional thin layer, a virtually one-dimensional nanowire or a minute heap of atoms, which physicists call a quantum dot and which, in some respects, resembles a single atom.

This physicist changed our world: It was Stuart Parkin’s developments in spintronics that first made Facebook and Google possible, as well as many other computer applications without which our everyday lives are now barely conceivable. Parkin has been Director at the Max Planck Institute of Microstructure Physics in Halle for one year now. For his colleagues there, his energy is impressive and challenging in equal measure.

Computers today serve as a jukebox, movie archive and photo album, and must thus provide fast access to ever-larger amounts of data. Scientists at the Max Planck Institute for Intelligent Systems in Stuttgart and the Halle-based Max Planck Institute of Microstructure Physics are paving the way for magnetic storage materials that make this possible, cleverly taking advantage of the unique laws of the nanoworld.

Magnetism in two dimensions goes easy-plane

2021 Bedoya-Pinto, Amilcar; Parkin, Stuart S. P. 

Material Sciences Solid State Research

The physics of low-dimensional systems has been a topic of great interest. Recently, two-dimensional (2D) materials exhibiting long-range magnetic order have been in the spotlight. Using state-of-the art molecular beam epitaxy, we constructed the first large-area 2D ferromagnet - a single CrCl3 monolayer on Graphene-on-Silicon-Carbide substrate - which exhibits an easy-plane magnetic anisotropy (2D-XY universality class). This discovery offers a suitable platform to observe exotic phenomena with application potential, such as 2D spin superfluidity and topologically protected magnetic textures.

Two-dimensional (2D) ferroics displaying magnetic, ferroelectric, or ferroelastic order have recently been discovered. These materials are attracting tremendous interest in the research community both because of the novel physics they host, as well as their potential for next generation nanoelectronics. Our institute explores, synthesizes and characterizes novel 2D ferroics with the aim of using them in innovative energy-efficient devices.


The growing zoology of skyrmions!

2019 Ma, Tianping; Saha, Rana; Parkin, Stuart

Particle Physics

Spintronics is a field of research that focuses on the fundamental physics and applications of spin-based phenomena. To date spintronics has played a key role in the development of recording heads that are used in magnetic disk drives and in a high-performance, solid-state, non-volatile magnetic random access memory. A third spintronics technology, the magnetic Racetrack memory, has the potential to supplant magnetic disk drives: this article discusses the discovery of several novel magnetic nano-objects, so-called “skyrmions” that could encode the data within Racetrack Memory.


What falling cats mean for density functional theory

2016 Requist, Ryan Tyler; Gross, Eberhard K. U.

Material Sciences Particle Physics Quantum Physics

Density functional theory, the most widely used method for calculating the properties of molecules and solids, is limited by its reliance on the Born-Oppenheimer approximation – the assumption that nuclei move infinitely more slowly than electrons. Research conducted at the Max Planck Institute of Microstructure Physics has overcome this limitation, exploiting recent advances in the concept of Berry curvature to establish a density functional theory that fully accounts for nonadiabatic coupled electron-nuclear motion.


Helical magnetism in iron nanoislands

2014 Sander, Dirk; Kirschner, Jürgen

Material Sciences Particle Physics Plasma Physics Quantum Physics Solid State Research

Two-dimensional iron islands, some thousand atoms small, exhibit a novel magnetic order on the nanometer scale, which was discovered by spin-polarized scanning tunneling microscopy. The local magnetization direction of iron rotates continuously over five nearest neighbor distances by 360 degrees. For iron, this magnetic order is unusual, and it is ascribed to the reduced dimensionality of the iron nanostructure. Structural relaxation within the nanostructure modifies the spin-dependent interaction between electrons, and a non-collinear spin alignment results.
