Low Temperature Local Structure of Multierroic of ReMn$_{2}$O$_{5}$

ORAL

Abstract

The temperature dependent structure of the REMn$_{2}$O$_{5 }$ (REe=rare earth) system has been examined by the Neutron and X-ray pair distribution function method based on high-q data. Comparisons with Rietveld and XAFS measurements will be made. The detailed temperature dependent structure on multiple length scales will be presented.
