Epitaxially oriented (1 0 0) and (1 1 1) Sr0.775Y0.225CoO3-δ thin films were grown on single crystal (1 0 0) and (1 1 1) SrTiO3 substrates by the pulsed laser deposition method. We observed the relatively small strain and the ferromagnetism with the relatively large grains in the epitaxial (1 1 1) Sr0.775Y0.225CoO3-δ thin film at room temperature. However, the epitaxial (1 0 0) Sr0.775Y0.225CoO3-δ thin film showed the relatively high strain along the in-plane orientation and the superparamagnetic property with the relative small grains.
