Interplay between 2D ferromagnetism and transport at the surface of FeSi
Interplay between 2D ferromagnetism and transport at the surface of FeSi
FeSi is a curious example of a $d$-electron system that manifests many of the same phenomena associated with $f$-electron Kondo insulators, including conducting surface states with potentially non-trivial topology. Here we investigate the magnetization and magnetotransport of these surface states and how a 2D ferromagnetic state at the surface of …
