Temperature dependent structural phase transitions of SrRuO{sub 3} thin films epitaxially grown on SrTiO{sub 3}(001) single crystal substrates have been studied using high-resolution x-ray diffraction. In contrast to bulk SrRuO{sub 3}, coherently strained epitaxial layers do not display cubic symmetry up to {approx}730 deg. C and remain tetragonal. The cause of this behavior is believed to be the compressive strain in the SrRuO{sub 3} layer due to the lattice mismatch with SrTiO{sub 3} substrate due to lattice mismatch. The tetragonal symmetry during growth explains the single domain growth on miscut SrTiO{sub 3} substrates with step edges running along the [100] or [010] direction.
