Abstract: In this talk I will present some of the recent resonant effects observed in spintronic devices in the presence of spin-transfer torque. I will discuss in detail the resonant switching , the isochronous and non-isochronous locking and the stochastic resonance. Analytical and numerical models will be presented in comparison with the experimental data.
