Description
Co2MnSi Heusler alloy thin films have been grown by cosputtering from three elemental targets. Changes in growth temperature and stoichiometry affect the film texture and the temperature dependence of the resistivity. However, the spin polarization of the transport current is insensitive to these changes, being of the order of 54% as determined by point contact Andreev reflection spectroscopy. Stoichiometric films are single phase, have a strong (110) texture, and a saturation magnetization of 1007 emu/cc (4.95 μB/formula unit) at 10 K
