Low-temperature synthesis, structural and magnetic properties of self-dopant LaMnO3+δ nanoparticles from a metal-organic polymeric precursor

Monophasic and highly crystalline Self-dopant LaMnO3+δ nanoparticles (72 nm) have been successfully synthesized at low temperature (773 K) by metal citrate complex method based on Pechini-type reaction route which showed ferromagnetic interaction. Surface areas of LaMnO3+δ nanoparticles were found to be 157.4 and 153 m2 g−1 for the samples annealed at 773 K and 1173 K, respectively.
