Popis:	57Fe Mossbauer spectra have been obtained at room temperature for (NdDy)TiFe11, and at 11K and room temperature for the corresponding nitrides (NdDy)TiFe11Ny. The magnetic behaviors of Fe atoms at different sites have been studied. We have found a larger increase of the hyperfine fields upon nitrogenation due to the higher nitrogen content in these compounds and got a bigger enhancement of the isomer shift in 8j site because of the nearest nitrogen environment.
