Abstract
The effects of pressure on the dielectric properties and phase transitions were investigated for a number of KTN compositions revealing the richness of phenomena involved. Crystals with x > 0.1 exhibit ferroelectric soft-mode behavior and for x ≂ 0.02 a pressure-induced ferroelectric-to-relaxor crossover occurs. The system also exhibits a pressure-induced crossover from classical-to-quantum behavior ultimately leading to the complete suppression of the phase transition and the formation of a quantum paraelectric state.
