摘要：

The electronic and magnetic properties of SrFeO3-delta single crystals with controlled oxygen content (0less than or equal todeltaless than or equal to0.19) have been studied systematically by susceptibility, transport, and spectroscopic techniques. An intimate correlation between the spin-charge ordering and the electronic transport behavior is found. Giant negative as well as positive magnetoresistance are observed.
