Results of Mossbauer measurements on Co-57-implanted beta-FeSi2 are reported. It is demonstrated that Co atoms are mobile during applied annealing. Co enters into both possible sites of iron with a slight preference for one of them. Because of this weak preferential occupancy of iron sites, two models can explain the Mossbauer spectrum equally well.
