摘要： 57Fe M?ssbauer spectra have been obtained at room temperature for (NdDy)TiFe11, and at 11 K 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.
