Effect of oxygen non-stoichiometry on the structural and magnetotransport properties of LaMn{sub 0.85}Cr{sub 0.15}O{sub 3+{delta}}

Thermogravimetry, X-ray diffraction (XRD), d.c. magnetization, high-temperature susceptibility and electrical resistivity measurements were performed for LaMn{sub 0.85}Cr{sub 0.15}O{sub 3+{delta}} perovskites with accurate control of the oxygen content (0{
