The stable phase structure of BiFeO3 films on LaAlO3 substrate was studied. In the biaxial constrained case, it changes from a tetragonal phase to a rhombohedral one with the increase of film thickness. By reducing the degree of the constrain from the biaxial case to the uniaxial one, the film relax...
