Anisotropy from the quadrupole scattering contribution to the electrical resistivity of magnetically ordered rare‐earth compounds is examined. Considering the conduction electrons in plane‐wave states, we find that the principal contributions to the anisotropic scattering come from thepanddpartial wave scattering. We take into account the crystal field splitting of the rare‐earth ions’ 4fnelectrons and therefore include the effects of inelastic scattering. We consider the case of zero magnetic field so that anisotropy only appears below the ordering temperature of the system. The theory is applied to dysprosium and holmium antimonide.
