Abstract

The magnetic properties of the [Tb–Co/Si]n films are studied at temperatures of 5–300 K. The regularities of changing the effective magnetic moment of terbium and the average magnetic moment of cobalt with decreasing magnetic layer thickness are determined. In this case, interlayer interfaces are shown to play the active role. A decrease in the Tb–Co layer thickness is accompanied by an increase in the opening angle of sperimagnetic cone and the transition from the sperimagnetic to speromagetic structure.
