Description

This study reports significant differences in the defect-mediated electrostrain in B-site trivalent ions (Fe3+ and Mn3+) doped Barium titanate based system. Electron Paramagnetic Resonance (EPR) Spectroscopy has been employed as a structural probe for understanding the symmetry of defects. Differences in the reorientation of the defect dipoles have been correlated with the electrostrain. Mechanism for the higher strain in Mn-doped system has also been explained.
