Abstract

A homogeneous SiO₂-Na₂O-Fe₂O₃ glass containing 4.6% Fe₂O₃ was prepared and devitrified to produce a glass ceramic containing the magnetic compound Na₅Fe(SiO₃)₄. The DC magnetic susceptibility measurements performed on both samples have shown that the magnetic ion-ion interaction is antiferromagnetic and is stronger in the crystallized sample. It was also shown that M versus H data at different temperatures do not collapse to a single curve in the M versus H/T representation, for either the glass or the heat treated sample. But the spread of the data is larger in the heat treated sample, further indicating a stronger interaction in the crystalline sample. The M versus H curves for the glass sample were fitted with Brillouin function by keeping the total number of magnetic ions constant and varying the proportion of ferrous ions until a best fit was achieved. The [Fe²⁺]/[Fe_total] ratio obtained from the fit is in good agreement with the value obtained from X-ray photoelectron spectroscopy (XPS) performed on the glass sample.
