摘要：

Structural, magnetic and magneto transport properties of La1-ySryMn0.5Co0.5O3 +/-delta perovskites prepared by aqueous solution combustion synthesis were studied in detail. The effect of Sr doping on the properties of these perovskites was investigated. As-prepared perovskites were characterized using X-ray diffraction for single phase formation. Magnetic study was carried out for in depth analysis of the magnetic properties. AC susceptibility study shows a change in the behavior of undoped and doped compounds in low temperature region. Ferromagnetic interactions was found to increase in the low temperature region in the doped compounds compared to that in the undoped compound. The measurements on resistivity showed reduction with Sr doping up to y = 0.5. This is attributed to the high spin stabilized Co3+ ions which enhance the ferromagnetic interactions and the hopping probability of e(g) charge carriers.
