One-step synthesis and characterization of nanosized MgFe2O4 particles by ultrasonic spray pyrolysis technique

摘要

We have directly synthesized nanocrystalline magnesium ferrite (MgFe2O4) powders by one-step Ultrasonic Spray Pyrolysis (USP) technique without any additives or post-annealing processes. Different pyrolysis temperatures were applied to the reactor furnace to obtain ferrite powders with different crystallite size. We investigated the crystallite size effect on the morphological and magnetic properties of the resulting nanosized MgFe2O4 particles.
