Hall conductivity and colossal magnetoresistance in FeSb2

ORAL

Abstract

We report the anisotropic Hall conductivity and discuss mechanism of colossal magnetoresistance in Co doped FeSb2. The Hall conductivity is described in a mutil-carrier picture, in which large carrier mobility was found in Co doped FeSb2.
