The theoretical research of reflection of bulk magnetoelastic waves in the ferromagnet with isotropic elastic properties has been investigated. It shows calculation of intensities of reflection and transmission of magnetoelastic waves at falling on the boundary of two semi-infinite uniform ferromagnets with different values of parameters of exchange interaction, uniaxial magnetic anisotropy and saturation magnetization; taking into consideration the coupling in the interface, which qualitatively changes the nature of frequency dependences of reflected magnetoelastic waves intensity and dependences on the external uniform permanent magnetic field.

In this paper, we calculate the dependencies of spin wave reflection intensity on frequency and external magnetic field for a ferrogarnet structure in an exchange mode, for which the influence of the magnetostatic part of the energy is neglected as compared with the exchange part. A ferrogarnet structure is chosen because it has a very small damping parameter and provides high-quality transmission of data.
