A series of La3+ doped nanoparticles of BiFeO3 multiferroic samples was prepared using solid state reaction. Structural and magnetic properties were investigated using XRD, TEM, magnetic susceptibility and M-H loop. All samples were antiferromagnetic in character. Maximum coercivity HC = 5265 Oe was obtained at x = 0.25. Improvement of the magnetization of BiFeO3 is achieved by La3+ at different doping levels.
