The new method devised for the measurement of the small heat changes which accompany step-by-step changes in the magnetization of ferromagnetic materials in fields of the order of a few hundred oersteds has been applied to the study of Armco iron in the annealed state and in the cold-drawn temper. Exceptional difficulties were encountered in the experiments, but the measurements appeared sufficiently reliable to permit a detailed analysis to be made of the energy changes in the several stages of the hysteresis cycle. Evidence was found for the existence of a kind of discontinuity in the magnetization of iron in fields of 350 to 400 oersteds predicted by Akulov and hitherto not observed experimentally.
