The spin-wave instability of self-oscillations in uniaxial nanopillar devices is studied.

Abstract
The spin-wave instability of self-oscillations in uniaxial nanopillar devices is studied. It is demonstrated that under certain conditions these self-oscillations are stable with respect to spin-wave perturbations. This theoretical result is consistent with experimentally observed stability of large angle self-oscillations driven by spin-polarized current injection.
