Abstract
Experiments with spherical iron particles 28 A to 265 A in diameter demonstrate that the proposed nonferromagnetic surface layer on an iron particle must be less than 1 A thick. This conclusion is based upon a comparison of the ferromagnetic iron indicated by magnetic saturation, and the total amount of iron as determined by chemical analysis.Keywords
