摘要：

Polycrystalline Sr2Fe1+ xRe1 xO6 samples have been synthesized and structurally characterized by X- ray powder diffraction, transmission electron microscopy and X- ray absorption spectroscopy. Resistivity strongly increases with x, but a large and negative magnetoresistance persists up to x = 0.33. This is discussed considering the charge delocalization in iron and rhenium t2g orbitals.
