## Abstract Domain structure and phase transition sequence of 0.91PZNβ0.09PT single crystal, grown from high temperature solution, have been analysed using polarised light microscopy. The domain structure of (001)~cub~ cut single crystal exhibit coβexistence of rhombohedral and tetragonal phases. T
This paper discusses the difference in permittivity at infrared frequencies between Ba(Mg 1/3 Ta 2/3 )O 3 (BMT) and Ba(Mg 1/3 Nb 2/3 )O 3 (BMN) based on a first-principles calculation. The permittivity, far-infrared and Raman spectra are successfully computed. Analysis of these results shows that th
