Description
The crystal chemistry, electronic structure, and electrical and magnetic properties of the novel perovskite-related nickel oxides Sr3Fe2-xNixO7-δ with 0==0.3. The electrical resistivity decreases with increasing Ni content as the p-p band gap tend to close due to the reduction of the Tσ value. Negative magnetoresistance (∼-24% for x=0.6 and -7% for x=1.0 at 20K and 9T) was observed for the Ni containing samples
