One step synthesis of highly crystalline and high coercive cobalt-ferrite nanocrystals

摘要

Highly crystalline and almost monodisperse spinel cobalt-ferrite nanocrystals are synthesized in a one step process,which has very high coercivity at 10 K and exhibits superparamagnetic behaviour at 300 K.Preparation and processing of fine magnetic particles have been the subject of extensive research over the last several decades due to their many technological applications including ferrofluids,data storage and medicine.
