Research Abstract

It is indispensable to establish effective means to generate, transfer, manipulate, and detect spin currents in order to develop spintronic devices based on spin dependent transport behaviors. In this project we set following three targets concerning generation and manipulation of the spin currents ; 1) exploration of materials which exhibit large spin Hall effects ; 2) establishing a means to rotate the spin accumulation vector ; 3) establishing a method to amplify the spin accumulation using superconductors. We have accomplished almost all the three targets as planned. More precisely we first demonstrated experimentally the intrinsic nature of the spin Hall conductance in 4d and 5d transition metals, exhibiting the d-electron number dependence, and also succeeded in inducing a large extrinsic spin Hall conductance in Cu by adding Ir impurities. Secondly we have succeeded in electronic manipulation of the spin accumulation vector. We have also found the MgO interface layer drastically enhances the spin injection efficiency and the spin accumulation. Finally we have established the way to inject the spin current non-locally into superconductors. Amplification of the spin current using superconductor remained to be accomplished.
