The paper is devoted to the general regularities, which are concerned with the influence of thickness of the individual layers of ferromagnet, the number of repetitions, and the temperature of heat treatment of the multilayers based on Co and Gd on their magnetic properties such as the coercivity, the saturation of magnetization, and the residual magnetization. As shown, the change of magnetic properties is caused by both the growth of interface imperfection and the formation of amorphous solid solution at the condensation stage. The heat treatment leads to both the partial destruction of interfaces and the increase of concentration of the solid solution in a system. The squareness ratio of hysteresis loops for systems at issue is close to one. In the case of change of orientation angle, the samples in a parallel geometry of measurement are characterized by the anisotropy of magnetic properties in a plane of film.
