Résumé     
Annealing in reducing atmosphere allows stabilization of the Sn4+, Sb5+, or Te6+ dopant cations in a lower oxidation state. Due to its stereochemical activity, the lone electron pair of the resulting Sn2+, Sb3+, or Te4+ favors the location of these species in low-coordination sites, immediately on the surface of the substrate-compound crystallites. This allows Sn-119, Sb-121, or Te-125 Mossbauer spectroscopy to be applied for studying the processes occurring at the solid-gas interface. Results of such studies, mainly devoted to the Cr2O3 antiferromagnetic substrate, were discussed, along with the prospects of searching appropriate substrate-compounds of other types.
