Abstract

A simple and effective method of solid state reaction followed by quenching process is used to prepare multiferroic Er³⁺ and La³⁺ doped BiFeO₃ ceramics. X-ray diffraction patterns indicated that these ceramics were of single-phase perovskite structure. Doping with La enhanced the dielectric, ferroelectric and ferromagnetic properties of BiFeO₃. A-site substitution with the La and Er ions has been found to suppress the spiral spin structure of BiFeO₃ giving rise to the appearance of room-temperature weak ferromagnetism. The enhanced multiferroic properties are attributed to the enhanced magnetoelectric interaction, which results from the La and Er substitution-induced destruction of the spin cycloid.
