摘要：

We investigated the magnetotransport properties in SrRu0.7Fe0.3O3-delta epitaxial thin film synthesized by using pulsed laser deposition. X-ray diffraction (XRD)theta - 2 theta and reciprocal space mapping scans showed strong peaks demonstrating high quality. The image of step and terrace at atomic force microscope scan image of the film showed a layer by layer growth mode of the thin film. The resistivity showed a significant decrease by applying magnetic field of 9 T, which could be described in terms of spin dependent scattering. The zero-field resistivity at low temperature (2 K-24 K) was fitted very well with a variable range hopping model. The observed negative magnetoresistance (T = 10 K, H = 9 T) was as high as similar to 20 %.
