Abstract :
An analytical study of magnetization dynamics in nanomagnets subjected to magnetic fields and spin-polarized electrical currents is discussed. It is shown how the presence of various dynamical regimes depends on magnetic properties of the investigated system, in particular, it is demonstrated that the magnetization response is different if we consider magnetic systems with either uniaxial in-plane or easy-plane anisotropy.
