Abstract

A bilayer of a ferromagnet and a normal metal driven by an rf magnetic field at the ferromagnetic resonance can sustain a dc spin accumulation that is generated by the spin current pumped by the moving magnetization parameter. We show that in the presence of spin-flip scattering in the ferromagnet a charge bias between ferromagnet and normal metal builds up that is reminescent of the Berger voltage in spin valves. A trilayer system consists of normal metal-ferromagnet-normal metal is also discussed.
