Here we demonstrate that defect-domain interactions during polarization reversal processes in ferroelectric materials result in a pronounced fine structu...<br/>[Phys. Rev.

Tokura<br/>In this Letter a detailed study of the electric field gradient (EFG) across the Pr_{1-x} Ca_{x} MnO_{3} phase diagram and its temperature dependence is given. Clearly, distinct EFG behavior for samples outside or inside the charge order (CO) region are observed. The EFG temperature dependence eviden...<br/>[Phys. Rev.
