摘要：
Systematic data on the structural state and magnetic properties of films belonging to the binary Dy100 -xCox system have been measured within broad ranges of compositions (0 <= x < 85), temperatures (5-300 K), and magnetic fields (0-70 kOe). It was found that in the absence of magnetic moment on Co atoms (x <= 50), the films are in an asperomagnetic state, in which a considerable and nonmonotonical concentration change in the principal magnetic characteristics is observed. In the region of x > 50, the films have a sperimagnetic structure. It has been shown that the quantitative description of spontaneous magnetization in such a state can be obtained in the molecular field model.
