Abstract
The particle sizes of four Fe and two Fe–Co powders with diameters ranging from 200 to 600 angstroms have been determined using electron microscope, x‐ray line broadening, and nitrogen adsorption techniques. Reasonable agreement was found between the electron microscope and the x‐ray methods, while the sizes determined through nitrogen adsorption were in every case larger. A method of dispersing single‐domain ferromagnetic powders for electron microscopy is described.Keywords
