Abstract: Magnetization curves of Co0.35(SiO2)0.65 granular film were measured from 70 up to 390 K. Although the anhysteretic magnetization loops could be well described using an integral of Langevin functions weighted by a distribution function of moments, the fitting parameters show an anomalous behavior. The median magnetic moments exhibit a low-temperature limit close to zero, and all have values well below the value expected from TEM analyses, with observed differences up to 82%. © 2003 Elsevier B.V.
