The influence of the thickness of the nanoscale ferrimagnetic Tb-Co layers on the magnetic properties of Tb-Co/Ti and Tb-Co/Si multilayers was studied. The fanning cone angle of Tb-Co sperimagnetic structure changes non-monotonously with a decrease of the Tb-Co layer thickness.

The results of magneto-optical and magnetometric measurements carried out on two-layer film structures of YIG/FeNi are presented. YIG films were grown by liquid-phase epitaxy, and FeNi films were deposited by magnetron sputtering. It has been established that an interlayer magnetic coupling takes place in the YIG/FeNi system, which is mainly due to magnetostatic interaction. Keywords: yttrium-iron-garnet, permalloy, interlayer coupling, magnetostatic and exchange interaction, magnetic domain structure.

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.
