Electric-field-controlled spin-wave coupling in lateral ensembles of magnetic microstructures

In this work, using numerical and experimental studies, we have demonstrated the possibility of controlling the dipole spin-wave coupling in a lateral array of ferromagnetic stripes using local deformations. As an experimental demonstration of the investigated physical processes, a configuration of a magnonic structure with a piezoelectric layer and structured electrodes on its surface is proposed, and the technique of laser ablation with spatial resolution is used to structure the piezoelectric layer. The mechanisms for controlling the dipole coupling of spin waves by creating elastic deformations localized in the region of the maximums of the electric field are revealed. From an applied point of view, the results obtained can be used to create a class of information processing devices, such as demultiplexing systems with frequency-space selectivity, controlled simultaneously by an electric and magnetic field.
