Abstract

The effect of Ba-substitution at Sr site on the structure, magnetoresistance and magnetic properties of La 0.67(Sr 1-xBa x) 0.33MnO 3 samples with x=0.00, 0.25, 0.50, 0.75 and 1.00 has been investigated. Single phase samples were obtained by a conventional solid state reaction method with rhombohedral (x=0.00) and orthorombic (x=1.00) structure. The grain size increases with Ba content. Low field magnetoresistance phenomenon at low temperature can be observed for all samples. However it vanishes at 300 K for x=0.75 and 1.00. The variation of MR% value is small ranging between 16 to 18% at 100 K in an applied field of 1 T. All samples show a single magnetic transition from the ferromagnetic (FM) state to the paramagnetic (PM) state as the temperature increases. Curie temperature, T c decrease with increasing Ba concentration.
