Pure and Mg-doped manganese oxide thin films were synthesized on heated glass substrates using the spray pyrolysis technique. The surface chemical composition was investigated by use of X-ray photoelectron spectroscopy (XPS). Structural morphological properties studied diffraction (XRD), scanning electron microscope (SEM) atomic force microscopy (AFM). Optical characterized UV-visible spectrosc...

After the discovery of the high-Tc superconducting oxides, many strongly correlated 3d electron systems have been reinvestigated. Recently, perovskite-type manganese oxides (R,A)MnO3 have been studied extensively. The above group of materials exhibit colossal magnetoresistance (MR) at the carrier doped region, which is interesting not only from the standpoint of strongly correlated systems but ...
