Synchronization of spin-transfer nano-oscillator by an external source

The dynamics of a spin-transfer nano-oscillator (STN) of the point-contact type under the action of a spin wave excited in the ferromagnetic layer by an external source is considered. It is shown that the STN can be synchronized by this external source, and the regions of synchronism capturing and holding in the space of parameters are established. Dependences of the spin-wave amplitude on parameters of the external signal are presented.
