Abstract

849,218. Magnetic compositions. STEATIT-MAGNESIAA. G., and STEATITE RESEARCH CORPORATION. Nov. 16, 1956 [Nov. 16, 1955 (2)], No. 35107/56. Addition to 849,217. Class 38 (2). Ferromagnetic ferrites having constricted hysteresis loops and comprising between 0.1% and 5% by weight of cobalt oxide added to mangagese-copper; manganese - magnesium, magnesium-zinc ; or magnesium cadmium ferrite, are produced as described in parent Specification. The allowable percentages by weight of the main constituents are shown by the areas ABCD in Figs. 5-8. Reference has been directed by the Comptroller to Specification 803,625.
