The resistivity of an amorphous ferromagnet is calculated in the multiple scattering approximation. The scattering at each magnetic site has a static component represented by a real parameter V which characterises the amount of disorder in the system and a dynamic component whose dominant contribution is the inelastic scattering of conduction electrons by diffusive modes associated with the longitudinal component of the magnetisation. For sufficiently large values of V the resistivity has a minimum as observed.
