摘要

Element-specific phase-resolved x-ray ferromagnetic resonance (FMR) was used to study spin pumping within Co_(50)Fe_(50)(3)/Cu(6)/Ni_(80)Fe-(20)(5) (thicknesses in nanometers) spin valve structures with large areas, so that edge effects typical of nanopillars used in standard magnetotransport experiments could be neglected.The phase of precession of the Co_(50)Fe_(50) fixed layer was recorded as FMR was induced in the Ni_(80)Fe_(20) free layer.The field dependence of the fixed layer phase contains a clear signature of spin transfer torque (STT) coupling due to spin pumping.Fitting the phase delay yields the spin-mixing conductance, the quantity that controls all spin transfer phenomena.The STT coupling is destroyed by insertion of Ta into the middle of the Cu layer.
