Filtration of Spin Wave Signals at Transmission of Data Through a Ferromagnetic Medium

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.
