Magnetic excitations in microcrystals

Keimer, Bernhard
A novel x-ray spectrometer allows accurate investigations of collective excitations in quantum materials, even if these can only be synthesized in microcrystalline form. The first experiments with this instrument, developed at MPI for Solid State Research, provide a microscopic explanation for the exceptionally high magnetic ordering temperature of a ruthenium compound whose origin had previously been mysterious. These results open up many new perspectives for the exploration of microscopic interactions and collective quantum phenomena in solids.
