Abstract: This work presents the results of the study of the magnetic properties of exchange-coupled film structures Tb-Dy-Co/FeNi obtained by magnetron sputtering. It is shown that an increase in the dysprosium content in the Tb-Dy-Co layer leads to an increase in the in-plane component of the magnetization of this layer, as well as to a decrease in the coercive force of the Tb-Dy-Co layer and a decrease in the exchange bias field of the FeNi layer at a temperature of 5 K. Changing the temperature of Tb-Dy-Co/FeNi films leads to a change in the order of magnetization reversal of the layers.

Keywords: multilayer magnetic films, interlayer exchange interaction, exchange bias, ferrimagnetism, magnetic compensation, permalloy.
