The Fe-57 NMR of Ce2Fe17Nx (x = 0-1.5) was measured in the ordered mag
netic state at 4.2 K. For x = 0, resonances coming from all Fe sites h
ave been identified in the 30-45 MHz range. With nitrogenation, new li
nes appear in the range 37-54 MHz. Every nitrogenated sample shows thr
ee sets of lines, arising from regions where Ce atoms have 0, 2, and 3
nitrogen atoms as near neighbors.
