Abstract

The temperature dependence of the electric-field gradient of 111Cd in single crystalline LiTaO3 was studied from room temperature to 1040 K in the ferroelectric and paraelectric phases. The data taken at room temperature show unambiguously the presence of two quadrupole interaction frequencies, νQ1=230 MHz and νQ2=242 MHz, with nonzero asymmetry parameters, while above the Curie temperature (TC=878 K) the data are well described by a unique frequency. The electric field gradient shows a usual temperature dependence, increasing aproximately in a linear fashion until TC and then decreasing faster. The initial increase is explained mostly by the lattice expansion, while above TC it is necessary to consider Li and O displacements.
