摘要：
In the framework of the random interaction fields method, the behavior of magnetic susceptibility is described in ferromagnetic materials, antiferromagnetic materials, and spin glasses. Phase diagrams for systems with competing exchange interactions are built. The conditions for the occurrence of different types of magnetic ordering are defined. The ferromagnetic Curie points for different numbers of neighboring atoms are calculated.
