摘要：

Bi(Fe1/2Cr1/2)O-3, a recently proposed candidate multiferroic perovskite, is prepared in a bulk form by high pressure solid-state synthesis. The material is isostructural with polar BiFeO3 but is paramagnetic at room temperature due to disorder of the Fe3+ and Cr3+ cations on the B site. Mossbauer and magnetization measurements show a transition to a cooperative magnetic state below 130 K. (c) 2007 American Institute of Physics.
