摘要	Single-phase Bil(1-x)Eu(x)FeO(3) (0 <= x <= 0.3) multiferroic ceramics were prepared to study the effects of Eu substitution on their crystal structure and ferroelectromagnetic behavior. X-ray diffraction studies revealed a sequence of the composition-driven structural phase transitions R3c -> Pn2(1)alpha (occurs at x = 0.2). Magnetic measurements revealed that Eu substitution can effectively induce the appearance of the spontaneous magnetization, which was significantly enhanced upon the composition-driven transition from a rhombohedral to an orthorhombic phase. The leakage current was found to be reduced on increased Eu concentration. The electric hysteresis loops were obtained in the Bi1-xEuxFeO3 ceramics, but the loops were not really saturated. The magnetoelectric coupling in Eu-doped BiFeO3 was estimated by the changes in the dielectric constant with an external magnetic filed. (C) 2010 Elsevier B.V. All rights reserved.
