摘要：

Highly dense, single-phase nanostructured ceramics of the 0.8BiFeO(3)-0.2BaTiO(3) multiferroic compound were prepared by mechanosynthesis. Their structural, microstructural and ferroic properties have been significantly improved by means of preventing the formation of residual phases through the mechanosynthesis protocol, mainly by the formation of a monoclinic solid solution (Cm space group), which is reported for multiferroic solid solutions for the first time. Improved remanent polarization and magnetization were obtained and determined as being 2.0 mu C cm(-2) and 0.02 emu g(-1). (C) 2009 Acta Materialia Inc. Published by Elsevier Ltd.
