Abstract: A magnetoelectric (“ME”) device is disclosed. In one aspect, the ME device includes a first piezoelectric substrate portion and a second piezoelectric substrate portion; a magnetostrictive body with a magnetization oriented in a first direction, the magnetostrictive body arranged on and extending between the first and second portions; a pair of input electrodes arranged on the first portion; and a pair of output electrodes arranged on the second portion. The input electrodes are configured to induce a fringing electric field extending between the input electrodes via the first portion, thereby causing a deformation of the first portion which in turn causes a deformation of the magnetostrictive body such that the magnetization thereof is re-oriented to a second direction due to a reverse magnetostriction. An output voltage is induced between the output electrodes by a deformation of the second portion caused by the re-orientation of the magnetization of the magnetostrictive body.

Abstract: A resonator for spin waves, wherein the resonator comprises a stack of material layers arranged on a substrate, a waveguide structure formed in at least one material layer in the stack and configured to propagate a spin wave and to confine a spin wave propagating in a waveguide element of the waveguide structure, such that a spin wave of a selected frequency propagating in the waveguide structure is arranged to resonate in the waveguide structure. The resonator further comprises a control mechanism formed in at least one material layer in the stack and configured to adapt at least one property of the waveguide structure for tuning the resonance frequency of the waveguide structure.
