Electrical resistivity of beta CoxGa1-x

Abstract

Electrical resistivity data on slow-cooled Co_xGa_1-x alloys with x=0.63, 0.60, 0.585 and 0.50 are reported. The negative temperature coefficient of resistivity obtained in the case of x=0.50 is discussed. The resistivity behaviour of alloys with x=0.63, 0.60 and 0.585 through their ferromagnetic-to-paramagnetic transition temperatures are analysed. It is proposed that the unusually large rho values are due to a contribution from the scattering of electrons by the highly anisotropic small magnetic clusters.
