Abstract

The analytical model is constructed for the description of the spin wave propagation through a system consisting of two ferromagnets without and with the Dzyaloshinskii–Moriya interaction, separated by a flat interface. The dependences of transmission and reflection coefficients of spin wave are found as a function of Dzya-loshinskii–Moriya constant which is known to be strongly temperature dependent, tending to a significant increase at low temperature.

Key words: ferromagnet, spin waves, Dzyaloshinskii–Moriya interaction.
