Growth and magnetic behaviours of La0.7Sr0.3MnO3 nanoparticles synthesized via thermal treatment method

La0.7Sr0.3MnO3 (LSMO) nanoparticles were synthesized by thermal treatment method using water as solvent and polyvinyl pyrollidone (PVP) as capping agent. The as prepared precursor was calcined at various temperatures ranging from 500°C to 1000°C. Structural characterization using X-rays diffractions...
