摘要：
The dielectric properties of [001]-oriented 0.76Pb(Mg1/3Nb2/3)O3-0.24PbTiO3 (PMN-PT24) crystal were investigated as a function of frequency and temperature under hydrostatic pressure. The dependence of remnant polarization of the PMN-PT24 crystal on pressure was also measured. The results showed that both the temperature of the maximum dielectric permittivity Tm and the depoling temperature Td of the PMN-PT24 crystal shifted to lower temperature, and the relaxor property became stronger with increasing hydrostatic pressure. The remnant polarization (Pr) of the PMN-PT24 crystal decreased linearly with increasing pressure. Consequently, the hydrostatic piezoelectric coefficient, dh, was calculated.
