Abstract. The question about influence of anisotropic properties of a ferrite film upon temperature coefficients of the basic types of magnetostatic waves is discussed. Films with cubic magnetic anisotropy and surface type of the wave are investigated in details. It is revealed that at magnetization along a <100> axis the temperature dependences of saturation magnetization and of anisotropy field partially, and in some cases completely, compensate each other, increasing thermostability of frequencies. Results of experimental investigations of yttrium iron garnet films are given.

Keywords: magnetostatic wave, ferrites, yttrium iron garnet, magnetic anisotropy, magnetization, temperature coefficient of frequency.
