- Abstract
- The properties of exchange spin waves (ESW) in epitaxial films of yttrium iron garnet (YIG) are investigated. A comprehensive analysis of the peculiarities of excitation, propagation, and interaction of ESW is carried out, taking into account their anisotropic properties. A methodology for calculating the dispersion and energy characteristics of waveguide modes of ESW for various directions of wave propagation in tangentially magnetized YIG films is proposed. It is established that the presence of both elliptical and linear polarizations of precession waves leads to the deformation of the magnetization precession vector's trajectory and a change in the orientation of the symmetry axes of the elliptic trajectory. Experimental confirmation of good agreement between calculated and measured characteristics of ESW is provided. The obtained results enable the creation of new types of functional devices for information transmission, storage, and processing based on short-wavelength exchange spin waves.
