Based on our findings, we propose that the pseudocubic structure of these perovskites presents a long-range tendency for cubic symmetry, while the short-range displacements bring the solid solution to a tetragonal symmetry. The results are discussed in terms of x-ray diffraction, structural optimized parameters, Raman spectroscopy, band structure, density of states, Mulliken charge, and overlap population.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-01-28T16:55:18Z No. of bitstreams: 1 10.1103-PhysRevB.75.144111.pdf: 288961 bytes, checksum: 6123cd8d2af1715af9c7cf3c832064f4 (MD5)Made available in DSpace on 2014-01-28T16:55:18Z (GMT).
