La0.1Bi0.9FeO3–BiY2Fe5O12 composites with simultaneously improved magnetization and polarization

La0.1Bi0.9FeO3–BiY2Fe5O12 (LBFO–BYIG) composites were fabricated via a modified solid-sate method by mixing the LBFO powder into BYIG solution and then sintering. The phase compositions, magnetic and electrical properties of the composites were investigated. The results show that the LBFO and BYIG phases can coexist in the composite without any secondary phase. Compared to the weak magnetic and ferroelectric properties of LBFO, the magnetization and polarization of LBFO can be simultaneously improved by the introduction of BYIG phase due to the high magnetization and resistivity of BYIG. The coercivity is reduced by the introduction of BYIG, due to the ferrimagnetic nature of BYIG.
