摘要：
The magnetic susceptibilities of Si and Si0.95Ge0.05 alloy whiskers of different diameters have been studied. Its significant difference from the magnetic susceptibility of a bulk material has been found. The presence of paramagnetic centers, some of which form magnetic nanoclusters in samples, is assumed. To explain the experimental results obtained, a model within Langevin superparamagnetism has been suggested. The distribution function of clusters over their magnetic moments has been constructed. The most probable sizes and magnetic moments of clusters are determined.
