A succession of relaxor ferroelectric transitions in Ba 0.55Sr0.45TiO3

Abstract

We present here the results of frequency dependent dielectric, polarization, and powder x-ray powder diffraction studies in the 300-100 K temperature range for Ba0.55 Sr0.45 Ti O3. The dielectric results indicate a succession of three relaxor ferroelectric transitions accompanying the cubic to tetragonal to orthorhombic to rhombohedral phase transitions confirmed by x-ray diffraction studies. © 2008 American Institute of Physics.
