TLDR
In this article, a single crystal of Pb(Zn 1/3 Nb 2/3 )O 3 was investigated in the ferroelectric and paraelectric temperature regions.Abstract:
The ferroelectric properties of a single crystal of Pb(Zn 1/3 Nb 2/3 )O 3 were investigated in the ferroelectric and paraelectric temperature regions The crystal undergoes a ferroelectric phase transition in a wide temperature range, changing from cubic perovskite structure to rhombohedral one A broad peak was observed in the dielectric constant vs temperature curve, being characteristic of the disordered perovskite ferroelectrics The spontaneous polarizations were obtained from the hysteresis loop and the pyroelectric current, and there was found a discrepancy in both measurements Without applying an electric field the optical anisotropy was not detected But with the field the domain and the birefringence were observed The effects of the dc field on the dielectric constant and the birefringence were observed over the wide temperature range A brief explanation of the character of the phase transition as well as dielectric and optical properties were givenread more

Dielectric and Magnetic Properties of Pb(Fe1/2Ta1/2)O3
TL;DR: In this paper, single crystals of Pb(Fe1/2Ta 1/2)O3 were grown from ternary melts with excess PbO. The crystals, having cubic perovskite structure at room temperature, undergo a ferroelectric phase transition at about 243°K, changing to rhombohedral structure.
