| Abstract: | The crystallographic and magnetic structure of YFe 10 Mo 2N 0 75 was studied by the powder neutron diffraction technique using a neutron triple-axia spectrometer at room temperature. The fractional occupancies of Mo and N atoms and the magnetic moments of Fe atoms were obtained by Rietveld analysis program FULLPROF. The intrinsic magnetic properties were discussed. |
