Outline of Final Research Achievements

We studied CPP-GMR devices using Co2Fe(Ga0.5Ge0.5) (CFGG) Heusler alloy for FM layers. New materials ofCsCl-type B2 alloys, NiAl, CuZn and AgZn, for the spacer layer. For NiAl, we prepared epitaxial layers with the different crystal orientations, [100] and [110], and examined the influence on the MR. The alloys CuZn and AgZn were selected as bcc alloys without heavy or magnetic elements for eliminating strong spin and spin-orbit scattering effects in the spacer layer. Large MR was observed for AgZn spacer layer. We also examined lateral spin valves using CFGG and showed that large output voltage is obtained by the high spin polarization of the Heusler alloys.
