Resumo
Equations for vector lines of the magnetic field and magnetic induction of a spin wave propagating perpendicularly to an external magnetic field in a dielectric–ferrite–dielectric structure tangentially magnetized to saturation and bounded on both its walls by a perfect conductor or a perfect magnetic wall are obtained. The vector line patterns of these magnetic quantities are calculated for the case when one of the dielectrics is a vacuum half-space. It is shown that the spin wave in a ferrite plate and in such structures may be considered as vortices of magnetic induction propagating in time and space. A relationship between the position of vortices of magnetic induction and the variation in the electric field of the spin wave is found. It is established that, in the structures under consideration, the vector lines do not form vortices.
