Abstract

The magnetic susceptibilities of powdered samples of Cs2CuGe5O12, Cs2FeGe5O12, Cs5NiSi5O12, Rb2CoGe5O12 and CsFeGe2O6 have been measured as a function of temperature. For the first four, the data show the transition metal ion to be in a distorted tetrahedral environment, in agreement with the expected pollucite-like structures. The data for CsFeGe2O6 are also consistent with this interpretation, but the results are less certain. An unusual feature of these materials is the substitution of a range of divalent transition metal ions into the aluminosilicate framework.
