Structural and magnetic properties in Mn-implanted, p-type Si were investigated. High resolution structural analysis techniques such as synchrotron x-ray diffraction revealed the formation of MnSi1.7 nanoparticles already in the as-implanted samples. Depending on the Mn fluence, the size increases from 5\phantom\rule0.3em0exnm\phantom\rule0.3em0exto\phantom\rule0.3em0ex20\phantom\rule0.3em0exnm upon rapid thermal annealing. No significant evidence is found for Mn substituting Si sites either in the as-implanted or annealed samples. The observed ferromagnetism yields a saturation moment of 0.21\ensuremathμB per implanted Mn at 10\phantom\rule0.3em0exK, which could be assigned to MnSi1.7 nanoparticles as revealed by a temperature-dependent magnetization measurement.
