Abstract: The magnetic properties of exchange-coupled Tb-Co/FeNi film structures obtained by magnetron sputtering were studied in a wide temperature range. It was shown that a decrease in the Zeeman energy when approaching the compensation temperature of the ferrimagnetic layer was accompanied by a change in the sequence of magnetization reversal of the layers. The efficiency of the interlayer exchange interaction varies with temperature very little.

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