The Magnetocaloric Effect in the Vicinity of the Magnetic Compensation Temperature of Amorphous Gd–Co Ferrimagnetic Films

The results of the study of the magnetic and magnetocaloric properties of amorphous Gd–Co ferrimagnetic films possessing perpendicular magnetic anisotropy in a wide range of fields and temperatures are presented. The interchange of the sign of the magnetocaloric effect in the vicinity of the compensation temperature occurs almost jumpwise in the case of orientation of the magnetic field perpendicular to the plane of the film and in a certain range of temperatures in the case of orientation of the field along the plane of the sample. The most probable reason for the diffusion of this transition is the appearance of a noncollinear magnetic structure.
