Abstract
Micromagnetic computations are used to describe spin-transfer driven ferromagnetic resonance in nanopillar spin valves with elliptical cross section. Analytical uniform magnetization models reproduce the resonance phenomenon adequately and these can be used to compute interface conductance. In this work, using the magnetic parameters extracted by fitting static magnetoresistance measurements, mixing conductances are obtained; these values are 25% and 20% lower than the ones previously reported. Nonuniform magnetization resonance is foundI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
