Effects of Annealing Temperature on Morphology and Dielectric Property of BiFeO3 Films Lili Zhang, Guoqiang Tanb, Meng Cheng, Huijun Ren and Ao Xia Key Laboratory of Auxiliary Chemistry & Technology for Chemical Industry, Ministry of Education, Shaanxi University of Science and Technology, Xi’an, Shaanxi, 710021, China btan3114@163.com Keywords: Multi-ferroic Material, BiFeO3 Thin Film, Dielectric Property, Sol-Gel Method Abstract.
Introduction BiFeO3 is a typical single phase ferromagnetic electric material and has the distorted perovskite structure.

In structures, marine, automobile, and industrial applications, the superior corrosion resistance of Zn and Zn-based alloys are well documented [29-31].

The corrosion resistance of steel depends on the passive ability and chemistry-phasics property of corrosion rust [5, 6].
Fig. 4 reveals that the corrosion products with cotton ball shape and flowery structure are formed, which corresponds to geothite and lepidocrocite, respectively [5, 6, 12], which is consistent with the result of XRD pattern (see Fig. 3).

Interfacial studies usually include identification of the interfacial structures and/or reaction products and determination of crystallographic relationship [14, 15].
