| Research Abstract |
Current-perpendicular-to-plane giant magnetoressitance(CPP-GMR) devices having low resistance and high MR outputs were developed by using Co-based Heusler alloys with high spin polarization. It was found that epitaxial films with a spacer layer of Ag gives remarkably high MR values. MR ratios exceeding 40% were obtained by using magnetic layers of Co_2FeGa_0.5Ge_0.5.
