摘要
Epitaxial thin films of ordered double-perovskite Sr2FeMoO6-y are deposited on (001) SrTiO3 substrates by pulsed-laser deposition using a two step growth process. Selection of growth conditions is found to lead to either highly conductive metallic thin films (residual resistivity of about 1 mu Omega cm) or semiconducting films. The metallic films show a positive magnetoresistance (MR) as high as 35%, while the semiconducting films show a negative MR of -3%, at a temperature of 5 K and a field of 8 T.
