In this work we present a feasibility study of epitaxial growth of thin films of strontium cobaltite, SrCoO<sub>3-\delta</sub>. The properties of strontium doped lanthanum cobaltite, La<sub>1-x</sub>Sr<sub>x</sub>CoO<sub>3</sub>, have been widely studied for dopant concentration x<0.5, but little work has been performed on the x=1 member of the series. The main issue is that this is not a thermodynamically preferable state and close to stochiometric SrCoO<sub>3</sub> in polycrystalline samples can only be obtained under high pressures of oxygen (>10kbar) or by electrochemical oxidation. However, theoretical calculations predict a phase change with</DISS_para>
<DISS_para>respect to strain in epitaxially grown samples, from ferromagnetic-metallic behaviour in the bulk state to insulating-ferroelectric-antiferromagnetic behaviour for strongly strained films. This provides strong motivation for epitaxial growth of SrCoO<sub>3-d</sub> films. In this work we will present a feasibility study by using the methods of high-pressure oxygen sputtering (typically 1.0-4.0mbar) on SrTiO<sub>3</sub>(001) and LaAlO<sub>3</sub>(001) substrates. As anticipated, the presence of oxygen vacancies is a severe problem, but also epitaxial stabilization of non-cubic phases, an unexpected issue, arises. These are found to grow in multiple orientations. Overall, the samples exhibit only weak or no ferromagnetism, even though bulk SrCoO<sub>3</sub> is known to be a strong ferromagnet. Based on the results, we present an outline for suggested further research on this topic.
