Abstract: The structure, magnetism, and transport in strained epitaxial [La.sub.0.5][Sr.sub.0.5]Co[O.sub.3] (001) films deposited on SrTi[O.sub.3] (001) substrates by reactive dc magnetron sputtering are examined. The results have shown a thin layer at the film/substrate interface with different structural properties to the bulk of the film, as well as a strongly graded magnetic and chemical profile at the film surface due to the significant roughness.
