Abstract
(SiO2)(1-x)Fe-x samples, with 0.2 less than or equal to x less than or equal to 0.4, were prepared by high energy ball milling. We studied i n these samples the temperature dependence of the magnetization, coerc ive force and thermally activated demagnetization parameters. From all these results it was concluded the occurrence, in all the examined sa mples, of two different maxima in the blocking temperature distributio ns, identified as corresponding to the extremes of the particle size d istribution.
