摘要：

Nanostructured BiFeO3-XTiO3 (X = Ba or Pb) multiferroic ceramics were processed by mechanosynthesis and a detailed structural study was conducted through Rietveld refinement of X-ray diffraction patterns. It was found that the structural and ferroic properties have been improved by the formation of double-phased compounds in both cases. In fact, ferroelectric investigations indicated a structurally tuned ferroic state, where the ferroelectricity is strongly affected by the coexistence of two distinct symmetries in BiFeO3-based solid solutions.
