Abstract
Micromagnetic computations are used to describe spin-transfer driven ferromagnetic resonance in a nanopillar spin-valve with elliptical cross section. Nonuniform magnetization resonance is found. With the aim of describing the resonance phenomena, an equivalent electrical circuit is proposed, and its electrical parameters are deduced from micromagnetic simulations. Comparisons of spin-torque nano-oscillators with conventional voltage-controlled oscillators are also providedI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
