Gaining insight into the characteristics of epitaxial complex oxide films isessential to control the behavior of devices and catalytic processes. It isknown that substrate induced strain, doping, and layer growth can affect theelectronic and magnetic properties of the film's bulk. In this study, wedemonstrate a clear distinction between the bulk and surface of thin films ofLa0.67Sr0.33MnO3 in terms of chemical composition, electronic disorder, andsurface morphology. We employed a combined experimental approach of X-ray basedcharacterization methods and scanning probe microscopy. X-ray diffraction andresonant X-ray reflectivity revealed surface non-stochiometry in the strontiumand lanthanum, as well as an accumulation of oxygen vacancies. Scanningtunneling microscopy showed a staggered growth surface morphology accompaniedby an electronic phase separation (EPS) related to this non-stochiometry. TheEPS is likely responsible for the temperature-dependent resistivity transitionand is a cause of a proposed mixed-phase ferromagnetic and paramagnetic statenear room temperature in these thin films.
