摘要

•BiFeO3 78÷534nm crystallites were obtained in microwave hydrothermal synthesis.•Crystallite thickness was controlled by PEG and increases with PEG concentration.•Samples were characterized by XRD, SEM, XPS and magnetic properties were studied.•Magnetic properties were found to depend on the crystallite thickness.•Enhancement of magnetization was related to size effect and surface Fe3+/Fe2+ spins.
