摘要：

Magnetic susceptibility studies have been done on xFe(2)O(3). (100-x)[3B(2)O(3).BaO] glasses with 0 < x < 50 mol%. For x < 10 mol% it was shown that the glasses studied obey a Curie law and only Fe3+ ions are present, but for higher concentrations the magnetic susceptibility is described by a Curie-Weiss law and both Fe3+ and Fe2+ valence states, which participate in antiferromagnetic interactions, axe evidenced.
