| Abstract: | Analytical expressions are derived for the derivatives of the frequencies of magnetostatic waves with respect to the external
magnetic field in anisotropic ferromagnetic films. Films having cubic anisotropy and 〈100〉, 〈110〉, and 〈111〉 surfaces are
analyzed in detail. The frequency-field relations are used in an experimental determination of the temperature coefficients
of the cubic anisotropy field and the saturation magnetization in an yttrium iron garnet film.
