Abstract
The origin of immiscibility of different components in crystals with the cooperative Jahn-Teller (JT) effect is analyzed. It is shown that in equilibrium states of partly disordered crystal systems with JT ions the phenomena of the restricted solubility regularly takes place. The same mechanism operates for the JT systems with the structural phase transitions (SPT) of the first and second order. It is associated with the tendency of JT centers to be in the phase with the maximum possible splitting of degenerate levels at low temperatures.
