Abstract

SrRuO₃ thin films have been grown in-situ on LaAlO₃ and textured metal templates by pulsed laser deposition. Deposition was carried out between 3 mTorr to 300 mTorr of oxygen partial pressure with laser repetition rate of 5 Hz. Substrate temperature was between 500 and 800°C. Dependence of out-of plane orientation of SrRuO₃ thin films on pressure and growth temperature is investigated by X-ray diffraction. The surface morphology and grain growth behaviors of SrRuO₃ thin films are analysed by atomic force microscopy. In addition, a ferromagnetic transition at ∼ 150 K of SrRuO₃ films on LaAlO₃ is detected by resistivity and magnetization measurement.
