A sample of Nd2Fe17Nxpreviously studied has been remeasured with higher‐resolution powder neutron diffraction. Rietveld analysis confirms the existence of two values ofx. The higherxcorresponds to nearly full occupation of the octahedral 9esite, while the lower value corresponds to partial occupancy of both the octahedral and tetrahedral 18gsites by nitrogen. The lattice changes for both compositions have been carefully examined. ©1996 American Institute of Physics.
