Abstract

A coating of iron carbide and carbon confers air-stability on the nanocrystalline iron particles that were prepared by sonolysis of [Fe(CO)5] in diphenylmethane followed by annealing of the as-prepared material. The saturation magnetization of this material (222 emug-1, see picture) is almost as high as that of bulk bcc iron.
