Ferromagnetic Magnetization

The iron-nickel-aluminium ternary system has been brought into prominence in recent years on account of its application in the permanent magnet industry. A study of some magnetic properties of this system has been made by Köster (1932-3), but his work is largely concerned with features other than those dealt with by the writer. An exhaustive X-ray examination of these alloys has been carried out by Bradley and Taylor (1938), and the information obtained has been used to throw light on the permanent magnetism in this system (Bradley and Taylor 1937 a, b, c ). Through the collaboration of Dr Bradley the writer has been able to make magnetic investigations on the same specimens as were used in the X-ray analysis, and the present account deals with a survey of the variation of the saturation intensity of these alloys with temperature. Owing to the complexity of the magnetic properties of alloys in this system, it is essential that the more fundamental properties should be the subject of the first investigation. The properties of ferromagnetic materials in low magnetizing fields depend to a considerable extent upon heat treatment, whilst on the other hand the saturation intensity in high fields shows less variation, and is in some degree a measure of the number of elementary magnets, presumably electron spins, contributing to the ferromagnetic magnetization of the particular alloy. Furthermore, the variation of the saturation intensity with temperature should give indications of any structure changes which may occur. A new method for the rapid measurement of saturation intensities for a few milligrams of substance over a range of temperature has been evolved (Sucksmith 1939) and the method there described has been used in the investigation on the nickel-iron-aluminium system.

AbstractQuantitative de terminations of thickness and composition are presented for 100- to 10,000-A iron-nickel films. Calibration of X-ray intensities with interferometric and calorimetric values give linear plots for films deposited on Mylar or glass substrates. Application of a film-casting technique shows promise of alleviating two of the problems encountered in X-ray spectroscopy, i.e., matrix-effect-caused deviations from proportionality and the lack of standards for calibration of many types of material.

By films of iron, nickel, and cobalt are here meant electrolytic deposits of these metals on platinised glass. The magnetic properties of such films are interesting in various ways. For example, when they are longitudinally magnetised, we have the case of a magnet where the ratio of length to breadth is very great, and where, consequently, the demagnetising force is very small, e.g., with a film of a 5000th part of a millimetre in thickness, and 5 mms. in length, we have a ratio in length to thickness of 25,000: 1; at the same time the film is so small that it can be tested in very high uniform fields.

The Subject

In 1903 Fr. Heusler published the discovery of an alloy consisting of manganese, aluminium, and copper, which, in spite of the fact that it contained none of the so-called magnetic metals, iron, nickel, or cobalt, possessed striking magnetic properties. Short accounts of work on the subject by Heusler and some other experimenters appeared, but on the whole the discovery seems to have aroused comparatively little interest in this country before August, 1904, when R. A. Hadfield exhibited a specimen of the alloy at the Cambridge meeting of the British Association. At the beginning of the winter session 1904 an attempt was made to obtain some of this alloy for the Physical Laboratory of Glasgow University, with the view of determining magnetic curves for the material, and of otherwise extending our knowledge of this interesting manganese bronze.
