Abstract

It is found that the Co₃O₄ nanowires, prepared by directly oxygenating cobalt foil, can keep an antiferromagnetic order until room temperature, quite different from other Co₃O₄ materials. The opposite behaviors of the M (T) curves under 100 and 6500 Oe, and the irreversible magnetic contributions at room temperature are observed. Detailed structural analysis and the splitting of energy levels in different crystalline fields show that the distortions of the crystal lattice make some nonmagnetic Co³⁺ ions have magnetic moment, which may possibly be the source for these novel behaviors.
