摘要：

A single-domain thermodynamic theory is employed to predict the spontaneous polarizations of (001)(c), (101)(c), and (111)(c) oriented epitaxial BiFeO3 thin films grown on dissimilar substrates. The effects of various substrate-induced strains on the spontaneous polarization were studied. The dependences of the spontaneous polarization on film orientations and the types of substrate-induced strains were analyzed. (c) 2007 American Institute of Physics.
