1054. ---------------. [FORESTIER, H., AND CHAUDRON, G.] [Thermomagnetic Study of Some Ferrites.] Compt. Rend., vol. 182, 1926, pp. 777-779; Chem. Abs., vol. 20, 1926, pp. 1939-1940. Curves showing the change in magnetization with temp. between 0° and 600° and 900° are given for Fe2O3·CrO, Fe2O3·NiO, Fe2O3·MgO, Fe2O3·CaO, Fe2O3·BaO, Fe2O3·PbO and Fe2O3·ZnO. The mean specific susceptibilities for these ferrites for fields 0-100 gausses are given as 0.102, 0.080, 0.078, 0.054, 0.0425, 0.0099, 0.0012, and 0.00016, respectively. |
