Resistance vs. time characteristics of LaxMnO3/normal metal junctions was studied in order to investigate the surface properties of epitaxial LaxMnO3 thin films. The change of the resistance of LaxMnO3/normal metal point contact was observed. The results are explained in the frame of oxygen out-diffusion from LaxMnO3 surface layer and creation of an insulating barrier from LaxMnO3 and/or metal.
