摘要：

Theoretical and experimental results are presented on spontaneous phase separation in nonsuperconducting degenerate magnetic semiconductors and high-temperature cuprate superconductors related to them. The following phenomena are considered: 1) the electronic phase separation, occuring at frozen impurity positions as a result of charge carrier concentration in regions with a changed magnetic ordering, 2) impuriry (chemical) phase separation when a nonuniform impurity distribution is simultaneously driven by interaction between impurity atoms and their tendency to concentrate in regions with a changed magnetic ordering.
