摘要：
The temperature dependence of the coercive field H-c is determined for a multilayer [Gd75 Angstrom/Si5 Angstrom/Co30 Angstrom/Si5 A](20) film with ferrimagnetic ordering of the magnetic moments of the cobalt and gadolinium layers. The maximum value of H-c is observed at a temperature of around 118 K, which corresponds to the compensation point of the film. It is established that in the entire interval of temperatures studied, the variation of the coercive field is due to the variation of the spontaneous magnetization.
