摘要

The doping of Mn in Si is attracting research attentions due to the possibility to fabricate Si-based diluted magnetic semiconductors. However, the low solubility of Mn in Si favors the precipitation of Mn ions even at nonequilibrium growth conditions. MnSi_(1.7) nanoparticles are the common precipitates, which show exotic magnetic properties in comparison with the MnSi_(1.7) bulk phase. In this paper we present the static and dynamic magnetic properties of MnSi_(1.7) nanoparticles. Using the Preisach model, we derive the magnetic parameters, such as the magnetization of individual particles, the distribution of coercive fields and the interparticle interaction field. Time-dependent magnetization measurements reveal aging and memory effects, qualitatively similar to those seen in spin glasses.
