Influence of cubic anisotropy on the temperature characteristics of magnetostatic waves in ferrite films magnetized in the film plane

Expressions for the temperature coefficients of frequency for magnetostatic waves in tangentially magnetized ferrite films having cubic anisotropy are obtained and analyzed. It is shown that in cases where the cubic axis lies in the plane of the film, temperature-induced changes in both the magnitude and direction of the external field can be used for thermostabilization of the frequencies. The problem of two-frequency thermostabilization is considered. The results of experimental investigations of the temperature characteristics of magnetization waves in a tangentially magnetized film of yttrium iron garnet with a {100} surface are presented. Zh.
