摘要: Abstract LSMO nanoparticles with core-shell structure have been synthesized by the non-aqueous sol-gel method and for comparison of their structural, magnetic, transport, electrochemical properties, non-core-shell citrate gel method. The structural analysis confirms formation nanostructure a ~2.3 nm shell layer nanoparticle. magnetic properties LSMO-CS are explained in terms exchange interaction between core disordered surface nanoparticles. transport examined help different conduction mechanisms involved temperature regions. low field magnetoresistance (LFMR) improved as compared to LSMO-NCS
