Concept of using structure magnonic crystal – ferroelectric – magnonic crystal as logic gate

The features of the propagation of spin waves in a composite multiferroic structure consisting of two magnonic crystals and a ferroelectric layer are considered. During the propagation of spin waves in such a structure, the formation of band gaps takes place, the position of which depends on the method of excitation of coupled structure and dielectric constant of ferroelectric. This effect can be taken as the basis for the operation of a logical element that allows implementing AND and OR operators. The results of theoretical and experimental studies of spin-wave processes in this structure are presented.
