Abstract
An apparatus for generation of an ultra-high frequency sound waves with frequencies between (1 GHz-10 GHz) is proposed. The apparatus comprises a spin injector, a tunnel junction, a conductive ferromagnetic material including magnon gain medium, a ferromagnetic dielectric material including magnetic phonon-gain medium, and an ultra-high frequency sound waveguide coupled to the ferromagnetic dielectric material. The spin injector is configured to inject minority non-equilibrium elections into the conductive ferromagnetic material via the tunnel junction. The non-equilibrium magnons generated in the magnon gain medium of the conductive ferromagnetic material propagate into the ferromagnetic dielectric material and having the magnon velocity exceeding the sound velocity in the phonon-gain medium of the ferromagnetic dielectric material cause generation of ultra-high frequency non-equilibrium phonons in the ferromagnetic dielectric material. The ultra-high frequency sound waveguide is configured to output the ultra-high frequency sound generated in the ferromagnetic dielectric material.
