Abstract Co-silicides were prepared with several techniques, such as annealing of evaporated Co-layers on a Si-substrate (silicide surface layers) and annealing of Co-implanted Si (buried silicide layers). By adding some57Co to the stable59Co, the formation of the various Co-silicides could clearly be followed as a function of annealing temperature by means of Mössbauer spectroscopy. In the case of surface silicide layers, Co2Si, CoSi and CoSi2 were formed subsequently. In the case of buried layers however, CoSi2 was the only crystalline phase that could be observed. In both cases, the CoSi2 spectra showed an anomalous side resonance. Moreover, it was found that when57Fe was implanted (instead of57Co), a drastic increase in the intensity of this side resonance could be detected by CEMS.
