Description
A facile and rapid glycine-assisted combustion method was developed to synthesize polycrystalline La0.8Ca0.2MnO3 (LCMO) powder by dissolving lanthanum nitrate, calcium nitrate, manganese nitrate (oxidant) and glycine (fuel) as the starting materials and water as solvent and then heating the resulting solution on a heating plate. The X-ray diffraction and FTIR analyses confirmed the orthorhombic crystal structure, and a morphological study showed the polycrystalline form of the LCMO powder. The calculated lattice constants a = 5.46, b = 7.73, and c = 5.49 A agreed well with the standard values. The magnetic measurements showed a paramagnetic behavior of LCMO at room temperature. The maximum change in entropy observed for the LCMO sample was -1.95 J/kgK at an applied magnetic field of 2 T at the Curie temperature of 165 K.
