Local and Long-Range High Pressure Structure of Orthorhombic REMnO$_{3}$

ORAL

Abstract

Orthorhombic perovskite REMnO$_{3}$ multiferroic systems were prepared by high pressure synthesis and solid state reaction. High pressure synchrotron x-ray diffraction and x-ray absorption measurements were performed to explore the structural changes. The influence of the pressure on the electrical polarization is discussed. Theoretical simulations are utilized to predict the stable magnetic phases based on the experimental parameters.
