Abstract

The magnetic environment of tin in the ferromagnetic superconductor RuSr2GdCu2O8 has been probed by doping Sn-119 ions onto the ruthenium sites. The transferred magnetic hyperfine interaction at the tin site was measured by Mossbauer spectroscopy in the temperature range 4.2-300 K. The spectra show two distinct tin sites. One has four ruthenium nearest-neighbour cations and the other three ruthenium and one tin nearest neighbours. The temperature dependence of the hyperfine fields indicates an ordering temperature of 108 +/- 5 K. The spectra favour parallel alignment of the field with the major axis of the electric field gradient indicating that the ruthenium moments are aligned along the crystallographic c axis.
