Structural and Magnetic Properties of Bottom-up Synthesized ZnFe_2O_4 Nanoparticles

摘要

Zinc ferrite nanoparticles are bottom-up synthesized and then peptized in aqueous media resulting in stable magnetic fluids. X-ray powder patterns are analyzed using Rietveld structure refinement and indicate the existence of cation inversion at the sites of the spinel-type nanocrystal. Magnetic and magneto-optical properties therefore arise and are investigated by static measurements performed on individual particles solutions.
