Title: Pressure driven ferroelectric to paraelectric transition in Sr doped BaTiO{sub 3}

High pressure Raman spectroscopy, X-ray diffraction, and dielectric measurements have been carried out in Ba{sub 1−x}Sr{sub x}TiO{sub 3} (x = 0.05 and 0.1). Detailed structural analysis revealed a single phase transition from tetragonal P4mm to cubic Pm3m symmetry. Increase in Sr ion concentration resulted in decrease in the phase transition pressure. The dielectric measurements showed considerable lowering of transition pressure which has been attributed to bulk behaviour of the material.
