The magnetic field and temperature dependences of static magnetic characteristics: magnetization, susceptibility, and paramagnetic Curie temperature of doped ferro‐, antiferro‐, and ferri‐magnetic semiconductors, are investigated within the mean field approximation. The case of deep impurities is considered, i.e. k B T C,N ≪ ϵ a . The general behaviour of the results is in agreement with the experimental data for some chalcogenides with spinel structure and those of rare earths. On this basis general conclusions are drawn, concerning the distinction between space homogeneous and inhomogeneous magnetic ground states.
