Magnetocrystalline Anisotropy and 3D Hopping Conduction at the Surface of FeSb2

Jarryd A. Horn, Yun Suk Eo, Keenan Avers +4

Motivated by the recent discovery of metallic surface states in the d-electron Kondo insulator candidates FeSi and FeSb2, along with some recent reports of magnetic correlations in…
