Pulsed Laser Deposition of ${\rm SrRuO}_{3}$ Buffers for Coated Conductor Applications

SrRuO3 thin films have been grown in-situ on and LaAIO3 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 800degC . Dependence of out-of plane orientation SrRuO3 of thin films on pressure and growth temperature is investigated by X-ray diffraction. The surface morphology and grain growth behaviors of thin films are analysed by atomic force microscopy. In addition, a ferromagnetic transition at ~150 K SrRuO3 of films on LaAIO3 is detected by resistivity and magnetization measurement.
