最近对Ru和Co/Ru多层膜的兴趣促使我们在4.2K下测量了它们在垂直于平面的电流几何结构中的性质。对于溅射样品,我们给出了Ru的电阻率,Cu/Ru和Co/Ru的界面比电阻,Ru的自旋记忆损失长度lsfRu,铜/Ru界面的自旋记忆损失几率,以及Co/Ru界面的自旋散射各向异性参数γ的结果。
Recent interest in Ru and Co/Ru multilayers stimulated us to measure their properties in the current-perpendicular-to-plane (CPP) geometry at 4.2 K. For sputtered samples, we present results for the resistivity of Ru, the interface specific resistances of Cu/Ru and Co/Ru, the spin-memory-loss length lsfRu in Ru, the spin-memory-loss probability at Cu/Ru interfaces, and the spin-scattering anisotropy parameter γ at Co/Ru interfaces.
