摘要：
A sample of Nd2Fe17Nx previously studied has been remeasured with higher-resolution powder neutron diffraction. Rietveld analysis confirms the existence of two values of x. The higher x corresponds to nearly full occupation of the octahedral 9e site, while the lower value corresponds to partial occupancy of both the octahedral and tetrahedral 18g sites by nitrogen. The lattice changes for both compositions have been carefully examined. (C) 1996 American Institute of Physics.
