Mutual Synchronization of Nanooscillators Coupled by Spin Waves

Abstract

The dynamic behavior of a system of two spin-wave-coupled nanooscillators with various values of coupling strength and frequency mismatch has been analyzed. The parameter space of the system has been divided into the regions of existence of synchronous and quasi-synchronous regimes, beats, and the regime of oscillation suppression. The regions of multistable behavior have been identified. The behavior at the boundaries of capture and retention regions has been studied. Dependences of the width of capture and retention bands on the strength of nanooscillator coupling have been obtained.
