Abstract
DR. L. C. JACKSON'S letter in NATURE of June 27, p. 981, points out the fact that an iron atom, known definitely to be ferrous, can have at least four distinct magnetic moments; namely, 26, 26.5, 27, and 27.5 when expressed in the magneton of Weiss. The purpose of this note is to present preliminary data tending to show that the magneton numbers for ferrous iron are not limited to 26–27.5, but can be 0 and 10 as well. Likewise, a ferric iron atom can have a magnetic moment corresponding to 0 and 10 magnetons in addition to the 29 magnetons usually obtained from measurements on simple paramagnetic salts. An example is included of an iron compound, the carbonyl, in which the iron certainly plays the part of a diamagnetic element.
