Abstract
The disclosed technology generally relates to semiconductor devices, and more particularly to a device configured as one or both of a spin wave generator or a spin wave detector. In one aspect, the device includes a magnetostrictive film and a deformation film physically connected to the magnetorestrictive film. The device also includes an acoustic isolation surrounding the magnetostrictive film and the deformation film to form an acoustic resonator. When the device is configured as the spin wave generator, the deformation film is configured to undergo a change physical dimensions in response to an actuation, where the change in the physical dimensions of the deformation film induces a mechanical stress in the magnetostrictive film to cause a change in the magnetization of the magnetostrictive film. When the device is configured as the spin wave detector, the magnetostrictive film is configured to undergo to a change in physical dimensions in response to a change in magnetization, wherein the change in the physical dimensions of the magnetostrictive film induces a mechanical stress in the deformation film to cause generation of electrical power by the deformation film.
