Anisotropic absorption of pure spin currents

Abstract:

Spin transfer in magnetic multilayers offers the possibility of ultra-fast, low-power device operation. We report a study of spin pumping in spin valves, demonstrating that a strong anisotropy of spin pumping from the source layer can be induced by an angular dependence of the total Gilbert damping parameter, a, in the spin sink layer. Using lab- and synchrotron-based ferromagnetic resonance, we show that an in-plane variation of damping in a crystalline leads to an anisotropic a in a polycry...
