dc.description.abstract | It was found by optical polarization microscopy and the EPR study that lithium niobate and tantalate crystals undergo irreversible lattice changes under anisotropic hydrostatic compression. Regions having different cell orientations were registered. The observed changes were explained in terms of ``strain switching'' of ferroelastic domains. Possible sequence of phase transitions in these crystals (Pm3m<->R (3) over bar3 c<->R 3 c) and the symmetry of the condensed soft modes ( R-25 and Gamma(15) , correspondingly) were obtained by the analysis of the Gibbs free energy under external pressure. | |
