Anisotropic spin relaxation induced by surface spin-orbit effects
Anisotropic spin relaxation induced by surface spin-orbit effects
It is a common perception that the transport of a spin current in polycrystalline metal is isotropic and independent of the polarization direction, even though spin current is a tensorlike quantity and its polarization direction is a key variable. We demonstrate surprising anisotropic spin relaxation in mesoscopic polycrystalline Cu channels …
