Abstract

BiFeO3 (BFO) nanoparticles were synthesized by the sol-gel method. X-ray diffraction and energy dispersive X-ray spectroscopy indicate no secondary phases are present, and the composition of the BiFeO3 nanoparticles was stoichiometric. Magnetic measurements show that the BiFeO 3 nanoparticles exhibit ferromagnetism with spin-glass-like behavior. The results were found to be related to size effects, which partially destroy the long-wavelength cycloid spin structure, and which induce ferromagnetism and spin-glass-like behavior due to diffusion of domain walls and pinning at the nanoparticle surface.
