Abstract
The magnetic, electrical and magnetotransport properties were also investigated. An enhancement in the low-field magnetoresistance (LFMR) for lower fractions of SA was obtained with respect to pure LSMO and higher fraction additions showed a decrease in the LFMR due to the higher separation distance between LSMO nanoparticles. The tunnel barrier thickness observed in these nanocomposites was correlated with the interparticle distance obtained by SAXS. The enhancement of magnetoresistance was attributed to the increase in the extrinsic disorder promoted by the SA addition and no enhancement due to intrinsic magnetoresistance of LSMO was evidenced.
