Giant anisotropic magnetoresistance and excess resistivity in amorphous U1-xSbx ferromagnets

U1-xSbx amorphous ferromagnets were prepared that show a magnetoresistance anisotropy (AMR) reaching 26% at 10 K, in a 50 kOe field. This is a striking result, since the AMR of typical amorphous ferromagnets does not exceed 1%. Large excess resistivity caused by domain walls is found to scale with 2, where is the tangent of the Hall angle. © 1990 The American Physical Society.
