Abstract
SrRuO3 thin films have been grown in situ on single crystal LaAlO3 substrates and textured metal templates which contain an MgO layer produced by an ion-beam growth method. Deposition was made of oxygen partial pressure in a range from 50 m Torr to 250 m Torr with laser repetition rate of 5 Hz. Substrate temperature was between 600 °C and 800 °C. Dependence of out-of-plane and in-plane orientation of SrRuO3 thin films on pressure and growth temperature was investigated by X-ray diffraction. The surface morphology and grain growth behaviors of SrRuO3 thin films were analyzed by atomic force microscopy and scanning electron microscopy. In addition, the transverse magnetoresistance value in a field of 4 and 8 T was measured in temperature range of 50-200 K and the ferromagnetic transition at ∼140 K of SrRuO3 films on LaAlO3 was detected by resistivity measurement. © 2007 Elsevier B.V.
