Abstract: We report about muSR measurements on SmFeAsO1-xFx which helped us to identifythe signature of diluted ferromagnetic inclusions, ubiquitous in the ironpnictides. These impurities are characterized by a Curie temperature close toroom temperature and they seem responsible for a non negligible magneticrelaxation of the implanted muons, that should not be confused with intrinsicpnictide properties.
