摘要：

The effects of Bi and Fe-excess on the structure, ferroelectric, leakage current and magnetic properties of BiFeO3 (BFO) thin films are reported. BFO with 5% excess exhibits no change in the structure with an improvement in leakage current properties in comparison to stoichiometric BFO. Raman spectroscopy of 10% Bi excess suggests a structural change from monoclinic to rhombohedral accompanied with an improvement of resistivity and ferroelectric polarization switching. A higher Fe-excess leads to the formation of pyrochlore Bi2Fe4O9 and gamma-Fe2O3 that cause an increase in conductivity at the macroscopic scale. The results are discussed in terms of Fe and Bi-excess effects on the defect structure of BFO. (C) 2011 Elsevier B.V. All rights reserved.
