Abstract

The structural and magnetic properties of Co2MnSi thin films grown on n-doped Si(110) and Si(100) substrates were studied and observed to have a strong dependence on annealing temperature (TA). At T A = 275-350°C, the Co2MnSi films exhibited the B2 phase with a (100) orientation and a magnetic moment on both substrates. The saturation magnetization (MS) of Co2MnSi thin films was observed to reach a maximum at TA = 300°C, above which it was found to decrease. We consider that at TA ≃ 300°C, the Co2MnSi thin films on Si substrates exhibited the (100) orientation, a high MS and a low roughness which might promote spin injection.
