Effect of cerium on the properties of iron-containing potassium aluminoborate glasses
The separation of the magneto-ordered iron-containing phases were studied in heat-treated potassium aluminoborate glasses having a concentration of Fe/sub 2/O/sub 3/ and a variable concentration of CeO/sub 2/. Faraday's method was used to measure the temperature dependence of the magnetic susceptibility. A complex compound of a garnet structure was formed on heat treatment, and the positions of the rare-earth ions were occupied by cerium and iron ions. It was shown that the ratio of the boron and cerium in the compound can change over a wide limit but that it is only necessary to achieve some minimal concentration of cerium oxide. The Moessbauer spectra was measured using a cobalt 57 gamma source.
