Abstract :
Summary form only given. Diluted magnetic alloy CuFe exhibits a logarithmic increase in the resistivity due to spin flip scattering at low temperatures. Provided that non-equilibrium magnetization is induced by spin injection in CuFe alloy, the spin flip scattering should be effectively suppressed, causing a depression of the increase in the resistivity. In this study, we report a novel approach to detect nonequilibrium magnetization in this fashion.
