Abstract
It is established that the magnetoelastic effect in ionic crystals can occu r only in the presence of metastable states of point defects. These states call be caused either by freezing of high-temperature state of these defect s or by mechanical loading in the process of dislocation introduction. The kinetics of the two-stage field-induced relaxation process in the subsystem of point defects in unloaded crystals is analyzed in terms of thermodynami cs of nonequilibrium processes.
