Crystal Structure and Magnetic Properties for Bi1-xEuxFeO3 Compounds

BiFeO3 (BFO) is a promising multiferroic material due to its high ferroelectric and antiferromagnetic ordering temperatures. Substituting partially Bi by Rare-Earth (RE) seem to be one way to enhance magnetization of BFO. In this study, crystal structure and magnetic properties for Bi1-xEuxFeO3 compounds are presented. When the Eu content was below 5% (x < 0.05), no significant improvement in magnetic properties was observed. However, when x < 0.20, ferromagnetism was induced. More particularly, at x = 0.20, the compounds experienced a drastically structural transition that governs also their optical properties
