Comparison of the Size of Spherical Particles of Iron, Cobalt, and Alloys of Iron‐Cobalt in Mercury as Determined by Various Methods

摘要

The sizes of particles prepared in mercury with diameters less than about 3000 Å were determined by electron microscope examination, analysis of the magnetization curve, calculation from the temperature dependence of magnetic remanence, tin adsorption, and analysis of their growth kinetics. The results of the various methods were found to be in reasonable agreement.
