摘要：
Fe2CoSn Heusler alloy nanoparticles were synthesized using co-precipitation method. The prepared samples were annealed at various temperatures (700 degrees C, 750 degrees C, 800 degrees C, 850 degrees C, and 900 degrees C) in N-2 atmosphere. The structural properties of Fe2CoSn Heusler alloy nanoparticles were analyzed using powder X-ray diffraction techniques. The structure of the Fe2CoSn Heusler alloy nanoparticles was found to be FCC superlattice of L2(1) disorder structure. The grain size of Fe2CoSn Heusler alloy nanoparticles was found to be 4.82 nm for 800 degrees C annealed samples and it gets increased for high annealing temperatures. Dislocation density was calculated to be 4.304 x 10(16) m(-2) for 800 degrees C annealed samples with low coercivity, low exchange bias, high susceptibility, and high saturation values.
