摘要

Highly conductive metallic oxide thin films of SrRuO₃ with single crystalline quality have been grown on (001) SrTiO₃ by using pulsed laser deposition. The films have a [00l] orientation with an in-plane relationship of [110]_SrRuO3 // [100]_SrTiO3. They have excellent metallic behavior with room temperature resistivity of ∼310 μΩ cm and a residual resistance ratio of about 7 at 4.2 K, the largest reported to date. A clear ferromagnetic transition at ∼147 K was detected by resistivity and magnetic measurements. However, the transition becomes blurred as the density-of-point defects increases in the films following a 400 keV proton irradiation with an accumulative dose up to ∼6.0×10¹⁶ ions/cm².
