Description
Summary:We report on the synthesis of La 0.7 Sr 0.3 Mn O 3 (LSMO) nanoparticles having perovskite structure and particle size of the order of 30 nm . The process involves citrate-gel synthesis, size filtering, and surface coating with a shell of octadecyl amine (ODA) using electrostatic interaction-assisted novel chemical route. Magnetic measurements show the Curie temperature of ∼ 360 K establishing the desired stoichiometry and phase. Fourier transform infrared studies bring out that the amine group of ODA interacts with the LSMO surface. Refluidization yields uniform redispersion of the coated and dried powder.
