摘要：

The magnetic structure of SmRu4P12 has been investigated by neutron diffraction. Long-range antiferromagnetic ordering with a propagating vector of q = (1, 0, 0) was observed below the metal-insulator transition temperature (T-MI = 16.5 K). Data obtained at T = 3.3 K were analyzed with dipole magnetic moments of mu = 0.30 mu(B) at Sm sites. The results suggest that the primary order parameter is the T-alpha, or T-beta octupole accompanied by strong mixing with T-alpha and dipoles.
