Magnetism, Charge Order and Giant Magnetoresistance in SrFeO 3-δ Single Crystals

Résumé

The electronic and magnetic properties of SrFeO 3-δ single crystals with controlled oxygen content (0≤ δ ≤ 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.
