ferromagnetism|fɛrəʊˈmægnɪtɪz(ə)m|
[f. ferro- + magnetism.
Gregory's use of ferromagnetism was independent of Thomson's use of ferromagnetic; in the preface to his Lett. Anim. Magnetism (1851) Gregory states that it resulted from his mishearing the (then new) word paramagnetism.]
The quality of being ferromagnetic; the phenomena exhibited by ferromagnetic materials. (Broadly including ferrimagnetism but in some contexts contrasted with it.)
1851W. Gregory Lett. Anim. Magnet. Pref. 15 Heat, light, electricity and ferro-magnetism. Ibid. Pref. 16, I understand by Ferro-magnetism almost the same as Dr. Faraday does by Para-magnetism; and I use the term in contradistinction to Vital or Animal Magnetism. 1930E. C. Stoner Magnetism iv. 74 Ferromagnetism is to be attributed to the spin moments of the electrons in the atoms and ions, and not to the spin moments of free electrons, which normally should give rise only to a small paramagnetism. 1957Encycl. Brit. IX. 186/1 Ferro⁓magnetism is the kind of magnetism associated with iron, cobalt and nickel and some alloys. 1966McGraw-Hill Encycl. Sci. & Technol. V. 229/1 Some materials exhibit a special form of ferromagnetism below the Curie temperature called ferrimagnetism. |
