Abstract: La_1-xSr_xMn_0.88Fe_0.12O₃ compounds (0.15<= x <=0.5) was prepared by the sol-gel technique. The effect of Fe doping on the magnetic properties, conductivity and magnetoresistance for La_1-xSr_xMnO₃ was investigated. Experimental results indicated that the Fe doping leads to a decrease in the ferromagnetic ordering temperature, an increase in the resistance, and an enhancement of magnetoresistance for the La_1-xSr_xMnO₃ system.
