AC susceptibility and 57 Fe Mossbauer spectroscopy measurements are reported for Fe 2+ aluminosilicate glasses. The frequency dependence of T f (over a range from 10 to 10 8 Hz) is described by a Fulcher law. This indicates a progressive spin freezing at T f , comparable with results reported in Co and Mn aluminosilicate glasses. At T<
