Temperature Dependent Properties of Perovskite Small R-Ion RMnO$_{3}$ Systems

ORAL

Abstract

Perovskite small ion E-type systems with radii smaller than that of Lu have been synthesized. The structure, heat capacity and magnetic measurements have been used to compare them with standard E-type systems such as LuMnO$_{3}$ and HoMnO$_{3}$. Analysis of the structure is combined with theoretical estimates to relate the electronically driven polarization with the atomic structure.
