摘要

The effect of Mn substitution on the multiferroic properties of YCrO3 and LuCrO3 has been investigated. Solid solutions of the type YCr1-xMnxO3 and LuCr1-xMnxO3 (x = 0.0-0.3) possess orthorhombic structures with Pnma and Pbnm space groups respectively. Both the series of materials show canted antiferromagnetic behavior with T-N decreasing with increasing x. They also exhibit ferroelectricity with the transition temperature decreasing with increases in x. The x = 0.3 compositions show improved magnetic properties with a ferroelectric transition in the 418-425 K range. (C) 2007 Elsevier Ltd. All rights reserved.
