Dipolar glass state in K1-xNaxTaO3

View publication

Abstract

The static dielectric susceptibility of K1-xNaxTaO3 and its field derivatives depend critically on temperature above the transition temperature Tg. Below Tg, the susceptibility is dispersive and reveals relaxation between marginally stable states. The transition from the paraelectric to the disordered polar phase thus has dual aspects, criticality and metastability, just the same as spin systems with infinite-range interactions. © 1986 The American Physical Society.
