摘要：

The spin‐disorder resistivity of amorphous ferromagnets is investigated in the temperature regimes 0 ≦ T ≫ TC and T ≫ TC. The resistivity is calculated within the force–force correlation function method up to the second order in the sd‐exchange constant. A simple structural model for a structurally disordered Heisenberg ferromagnet is presented. At lowest temperatures the spin‐disorder resistivity varies as T3/2 for a sufficient high degree of disorder. It is concluded that the experimentally observed T2‐dependence at these temperatures is of non magnetic origin. This dependence can be qualitatively understood if the thermal smearing of the structure factor is taken into account. Copyright © 1979 WILEY‐VCH Verlag GmbH & Co. KGaA
