Origin of magnetic anisotropy in a 2D magnet

Scientific Achievement: Identified mesoscale phase separation and a corresponding variation of magnetic anisotropy driving the formation of spin textures in high-ordering temperature ferromagnet Fe5-xGeTe2 (FGT).Significance and Impact: Established a direct, quantitative relationship between local magnetic anisotropy and Fe-vacancy distribution in FGT, enabling logical design of magnetic properties.DOI: 10.1002/adma.202515150

Advanced Microscopy Brings New Insights to Heat

This measurement is correlated directly to ultrahigh energy-resolution monochromated electron energy-loss spectroscopy (EELS) measurements, which are able to directly measure the phonon response at the nano-length-scales of the long and short-period superlattices studied with DFT.
