Av. Kityk et al., ON THE ACOUSTIC PROPERTIES OF CSD2PO4 AND RBD2PO4 CRYSTALS NEAR PHASE-TRANSITIONS UNDER HYDROSTATIC-PRESSURE, Journal of physics. Condensed matter, 6(3), 1994, pp. 699-712
The influence of hydrostatic pressure on the temperature behaviour of
acoustic properties in the vicinity of phase transitions of CsD2PO4 an
d RbD(2)P0(4) crystals is studied. The pressure-temperature phase diag
rams are obtained. The results are considered within the framework of
phenomenological theory.
