Magnetic ordering and an extraordinary anomalous Hall effect in the itinerant ferromagnet Fe3Sn2

DOI

-Fe3Sn2 is a rare example of a ferromagnetic metal. It features a giant Anomalous Hall Effect (AHE) at room temperature that makes it a candidate material for spintronics applications. The magnetism is Fe3Sn2 starts from an apparently simple ferromagentic transition at ~640K where the moments point along the c-axis. On cooling the moments cant away from this direction and start to rotate into the kagome (ab) plane. During this process they also turn from being collinear creating spin chirality that is presumed to be the key to the observed AHE. Below ~80K the material adopts an unusual reentrant spin glass phase where a spin glass component coexists with the ordered ferromagnetic structure. We propose to use WISH to determine how the magnetic structure changes on cooling from paramagnetic to the re-entrant spin glass phase.
