Abstract

We report on a 69Ga and 205Tl NMR study of single-crystal thallium gallium selenide. Our findings show that transformation from the high temperature paraelectric phase to the low temperature ferroelectric phase occurs via an incommensurate phase that exists in the temperature range from Tc = 107.5 to Ti = 118K. On approaching phase transition at Ti from above, the crystal exhibits soft mode behavior, which is somewhat different for thallium and gallium substructures. Redistribution of 69Ga line intensities with temperature in the ferroelectric phase indicates a variation of the domain structure of this phase.
