abstract = "Using Landau-Devonshire(LD)-type phenomenological model, we investigate the phase diagrams and in-plane anisotropic misfit strains of single-domain single-crystal (110) Ba0.6Sr0.4TiO3 film epitaxially deposited on (001) NdGaO3 substrate. Investigation indicates that film thickness plays a crucial role on formation of in-plane anisotropic misfit strains and stable phases. As is consistent with results of experiment that anisotropic strains have greatly changes with increase of film thickness. The anisotropic strains induce tetragonal phases which only contain in-plane spontaneous polarization component. These phases do not exist in BST films of the same composition under isotropic strains. Moreover, calculation manifests that anisotropic in-plane misfit strains are almost completely relaxed when film thickness is larger than 600nm, which has been reported in experiment.",
