Abstract

The magnetic sublattice susceptibilities of atoms on the cubic and hexagonal sites of metallic Nd have been deduced from polarized-neutron-diffraction experiments over the temperature range from 1.7 to 100 K. Above 40 K both sites have the same susceptibility. Below the N\'eel point of 19.9 K the cubic site has a much larger susceptibility. Both susceptibilities have a cusp at the N\'eel point and a broad maximum near 8.5 K. The maximum covers the temperature region where anomalies have been reported in the specific-heat and neutron-diffraction data. These results are consistent with proposed models of the magnetic structure. The average of the two susceptibilities is in fair agreement with bulk susceptibility measurements.
