Resistivity and magnetoresistance anisotropy associated with s, p impurities in ferromagnetic Ni and Co

摘要: The authors have measured the electrical resistivity between 4.2K and 300K, longitudinal transverse magnetoresistance at 4.2K, of several dilute Co Ni based alloys containing various s, p impurities such as Sn Sb. deviations from Matthiessen's rule (DMR) derived data been analysed in terms two current model Campbell et al. (1968) values for alpha (the ratio spin up to down resistivities impurity site), mu same host sites) D coefficient mixing term) estimated. bulk these yield approximately=1 impurities, expected on basis a simple virtual bound state picture. also close 1, but there are systematic differences experiment predictions model.
