Abstract: The microstructure and chemical bonding states of pure and Ce-doped BiFe[O.sub.3] (BFO) films are characterized by scanning electron microscope (SEM) and Raman spectrum. The enhanced magnetic properties for the [Bi.sub.1-x][Ce.sub.x]Fe[O.sub.3] (BCFO) films are attributed to the presence of [Fe.sup.2+] caused by oxygen vacancies, the suppressed spiral spin structure, and/or the increase canting angle induced by Ce doping.
