Effects of Single-Substitution and Co-Substitution on BiFeO₃ Nanoparticles

Abstract:

Multiferroic BiFeO₃ nanoparticles have been prepared by solgel method. The effects of single-substituted and co-substituted on the structures and magnetism of all the samples are investigated systematically. X-ray diffraction and Raman spectra results confirm that the samples simulate from a distorted rhombohedral structure to a cubic structure. Surface morphology of the samples were examined by scanning electron microscope (SEM). The ferroelectric and magnetic hysteresis loops shows coexistence of magnetism and ferroelectricity in the room temperature. The structure transition may be the main cause for the origin of improved magnetic and ferroelectric properties.
