AbstractThe epitaxial growth of bilayer film made of ferromagnetic metal material Pr0.7Sr0.3MnO3 and charge-ordering insulating material La0.5Ca0.5MnO3 on single crystalline SrTiO3 (001) substrate. High resolution X-ray diffraction and atomic force microscopy analyses show the single crystalline nature of the film. Further atomic force microscopy measurement shows the presence of non-stoichiometric large particulates at the film surface, imparting an overall inhomogeneous composition to the film. This implied that the variation of crystalline structure occurred due to inhomogeneous composition. Magnetic measurement results indicate that the inhomogeneous composition could cause inhomogeneity of magnetic phase which in turn reduce ferromagnetism and enhance exchange bias effect.
