Abstract

The magnetoresistance of epitaxial Nd_0.7Sr_0.3MnO_δ thin films has been studied. A giant magnetoresistance, with more than 4 orders of magnitude change in resistance (-ΔR/R_H>10⁶%), was obtained at ∼60 K and a magnetic field of 8 T. This giant magnetoresistance (GMR) ratio is about one order of magnitude larger than the highest value reported previously which was observed in La-Ca-Mn-O film. We have also obtained a large GMR ratio with -ΔR/R_H>3000% for H=5 T in an in situ Nd_0.7Sr_0.3MnO_δ thin film, a much larger effect than the previous results in doped manganese oxide films in which a large GMR ratio was obtained only in postannealed samples. Our results also show that the GMR effect in these films can be strongly influenced by the thin-film preparation conditions.
