dc.description.abstractLead-free and multiferroic 0.7BiFeO<inf>3-</inf>0.3BaTiO<inf>3</inf> ceramics doped with K (0.5, 1.0, 3.0 and 5.0 mol%) have been successfully prepared by a solid state mechanical milling technique. The single phase perovskite was found at calcination temperature of 900?C for 6 h. The effects of K doping on the crystal structure, microstructure, magnetic and electrical properties of lead-free 0.7BiFeO<inf>3-</inf>0.3BaTiO<inf>3</inf> ceramics were investigated and discussed. The fracture micrographs of specimens elucidate the grain growth behavior with increasing K content up to 3.0 mol%. The weak ferromagnetic and ferroelectric properties were observed in rhombohedrally- distorted 0.7BiFeO<inf>3-</inf>0.3BaTiO<inf>3</inf> perovskite ceramic. However, the addition of K into 0.7BiFeO<inf>3-</inf>0.3BaTiO<inf>3</inf> has been found to improve the ferroelectric and ferromagnetic properties, with the optimized properties obtained at 3.0 mol% content of K.
