Abstract

Rare earth metal oxide perovskite structure Lanthanum ferrite nanocrystalline powder was prepared by solution combustion synthesis using Hexamine (HMTA) as a fuel and the fuel to oxidizer ratio is taken as a one (ψ = 1). The lanthanum ferritenanocrystallite was characterized by X-ray Diffraction, thermal gravimetric and differential thermal analyzer and Scanning electron microscopy with Energy dispersive X-ray spectrometer, FTIR and vibrating sample magnetometer.As-prepared nanopowder is observed as orthorhombic structure, thermal stability and morphology studies with elements contain the analysis of the material indicates a fabulous LaFeO3 material is formed. The magnetic properties shows low coercivity and low saturation magnetization for the LaFeO3 nanoparticles.

Keywords
