Present study describes the synthesis of nanocrystalline lanthanum orthoferrite by co-precipitationmethod using ethanol as a solvent. LaFeO3 nanopowders formed after annealing the precursor attemperatures of 700, 800 and 900 ºC for 1 h, have a particle size in the range of 30-50 nm. Accordingto XRD analysis, an increase in the annealing temperature from 700 to 900 ºC leads to an increase inthe average crystallite size from 43.76 to 62.80 nm and a decrease in the unit cell volume of about241.90 to 240.66 Å3. Synthesized LaFeO3 nanoparticles have strong absorption in ultraviolet(~ 200-400 nm) and visible light (~ 400-600 nm) and are soft magnetic materials with highmagnetization.
