Abstract:
The magnetic and magnetocaloric properties of amorphous ferrimagnetic Gd-Co films with perpendicular magnetic anisotropy were studied in a wide range of fields and temperatures. The change in the sign of the magnetocaloric effect near the compensation temperature occurs almost abruptly when the magnetic field is oriented perpendicular to the film plane. In a certain temperature range, it happens when the field is oriented along the plane of the sample. The most probable reason for the blurring of this transition is the appearance of a non-collinear magnetic structure.
