Abstract

Numerical and analytical analysis is used to explain recently observed experimental phenomenon - excitation of spin waves in spin valves due to the applied spin polarized current. Excited spin waves are being identified and Lyapunov stability analysis is being used to identify different regions of stability depending on the value of the applied current.
