SrRuO3 thin films have been grown in-situ on LaA1O3 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 LaA1O3 is detected by resistivity and magnetization measurement. [ABSTRACT FROM AUTHOR]
