论文摘要
通过自旋轨道耦合引起的旋转旋转通过界面的不连续性的特征是自旋记忆损失（SML）参数δ。我们使用第一原理散射理论和最近开发的局部电流方案来研究Au | pt，au | pd，py | pt and co | pt接口的SML。我们发现非磁性界面的温度依赖性最小，并且对涉及旋转障碍的涉及铁磁体的界面具有很强的依赖性。对于CO | PT的SML比PY | PT大，因为界面更突然。晶格不匹配和界面合金强烈增强了Au | pt比Au | Pd接口大的SML。接近性诱导的PT磁化的作用可以忽略不计。
The discontinuity of a spin-current through an interface caused by spin-orbit coupling is characterized by the spin memory loss (SML) parameter δ. We use first-principles scattering theory and a recently developed local current scheme to study the SML for Au|Pt, Au|Pd, Py|Pt and Co|Pt interfaces. We find a minimal temperature dependence for nonmagnetic interfaces and a strong dependence for interfaces involving ferromagnets that we attribute to the spin disorder. The SML is larger for Co|Pt than for Py|Pt because the interface is more abrupt. Lattice mismatch and interface alloying strongly enhance the SML that is larger for a Au|Pt than for a Au|Pd interface. The effect of the proximity induced magnetization of Pt is negligible.
