摘要：

The results of the temperature dependence of the magnetic susceptibility on xCoO .(1 - x)[2B(2)O(3) . SrO] glasses with 0 < x less than or equal to 50 mol% are reported. The effective magnetic moment values suggest that the Co2+ ions are predominantly octahedral coordinated in low CoO content glasses, whereas in higher CoO content glasses the Co2+ ions are located in tetrahedral sites. Also theta(p) values indicate that the Co2+ ions participate at the negative superexchange interaction for x greater than or equal to 20 mol%. Copyright (C) 1997 Elsevier Science Ltd.
