Abstract

For the first time, magnetoelectric and multiferroic properties of single phase polycrystalline Bi0.85Sm0.1Ho0.05FeO3 ceramic is reported here. BiFeO3, Bi0.9Sm0.1FeO3 and Bi0.85Sm0.1Ho0.05FeO3 are prepared by conventional solid-state route. The Rietveld refinement analysis explains the occurrence of distortion in rhombohedral phase with respect to host BiFeO3. The remanent polarization and hence magnetization of Bi0.85Sm0.1Ho0.05FeO3 ceramic are found to be significantly improved to some extent than BiFeO3 and Bi0.9Sm0.1FeO3. Magnetic field coupled to ferroelectric loop tracer and temperature dependent dielectric permittivity shows the signature of magnetoelectric coupling present in the sample.
