Physical Review B
Earlier atomic d-state models of anisotropic magnetoresistance / are reviewed and found to suffer from a weak-ferromagnetism catastrophe: a nonphysical finite value of / as exchange splitting goes to zero. New calculations of /, including cubic anisotropy, avoid this problem and offer a new paradigm for interpreting experiments on systems with various band structures: dilute polycrystalline nickel alloys with virtual-bound-state (VBS) and non-VBS impurities, and also weak concentrated ferromagnets like Fe-Ni Invar. p states are also found to give nonzero / in an atomic model. © 1986 The American Physical Society.
