论文摘要
我们研究了S波超导体/铁磁金属的接近效应，该金属具有Rashba自旋轨道耦合/扩散的正常金属连接，以及S波超导体/非结合磁性金属/扩散的正常金属连接。我们显示了由于中间磁性区域中的自旋叉散射，在扩散正常金属中的相等自旋三个配对的产生。旋转三曲线奇数库珀配对的出现可以在扩散正常金属中的状态的准粒子密度中产生零能量峰。
We investigate the proximity effect in an s-wave superconductor/ferromagnetic metal with a Rashba spin-orbit coupling/diffusive normal metal junction and an s-wave superconductor/noncollinear magnetic metal/diffusive normal metal junction. We show the generation of equal spin-triplet pairings in the diffusive normal metal due to spin-flip scattering in the intermediate magnetic regions. The emergence of the spin-triplet odd-frequency Cooper pairings can generate a zero-energy peak in the quasiparticle density of states in the diffusive normal metal.
