Magnetism, Charge Order and Giant Magnetoresistance in SrFeO$_{3-δ}$ Single Crystals
arXiv:cond-mat/0310695 · doi:10.1103/PhysRevLett.92.037202
Abstract
The electronic and magnetic properties of SrFeO$_{3-δ}$ single crystals with controlled oxygen content ($0 \leq δ\leq 0.19$) 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.
