摘要：

The crystal and magnetic structures of the TbNi2Mn compound have been refined by the Rietveld analysis of neutron powder-diffraction data. The compound has a cubic C15b-type structure, in which Mn atoms partially occupy both the 4a and 16e sites. Bulk magnetization measurements revealed magnetic ordering below the Curie temperature T-C=142 K. The values of magnetic moment are different for the Tb ion at the 4a and 4c positions. In the 4c site, the Tb moment is determined to be 5.4 mu(B)/Tb ion. The low value of the Tb-ion moment is indicative of the formation of a random magnetic anisotropy.
