The Variation of the Initial Susceptibility with Temperature, and the Variation of the Magnetostriction and Reversible Susceptibility with Temperature and Magnetization in Nickel
Abstract
This research is a sequel to an investigation, previously reported, of the variation of Young's modulus and internal friction with magnetization and temperature in a specimen of annealed, polycrystalline Mond nickel. The specimens used in both researches were cut from the same bar of material and annealed in the same manner. Complete data are given which show the variation of the initial susceptibility with temperature and that of the magnetostriction and reversible susceptibility with temperature, magnetization and magnetizing field between 21°C and the Curie temperature. The course of the initial susceptibility vs. temperature curve indicates a transition of the direction of intrinsic magnetization of the elementary domains in nickel from 111 to 100 at about 200°C. Further discussion of the results, in accordance with the domain theory of ferromagnetism, will appear in a subsequent paper by W. F. Brown, Jr.
