We stabilized SrRu0.9Fe0.1O3 single-crystalline films on SrTiO3 (001) and SrTiO3 (110) substrates using epitaxial strain during thin-film growth. X-ray diffraction (XRD) θ–2θ scans showed strong peaks demonstrating single-crystal quality. Fe doping in SrRuO3 had negative effects on the ferromagnetic properties, such as decreasing the Tc and saturated magnetic moment, as well as weakening the ferromagnetism. The negative effects were reduced when a suitable surface of the cubic substrate was selected for thin-film SrRuO3 growth. We found that the ferromagnetic properties, such as the Tc and saturated magnetic moment, differed depending on the substrate surface. The observed differences are discussed in terms of Ru–Ru nearest-neighbor distance.
