摘要：

The magnetic ordering of NpBi has been determined by neutron diffraction on a single crystal. NpBi orders antiferromagnetically in the triple-k type-I structure (k = \0 0 1\, m(k) parallel-to k) below T(N) = 192.5 K. The ordered magnetic moment develops at T(N) with a critical exponent beta = 0.31 +/- 0.02 an increases continuously on cooling to reach a value of 2.48-mu(B)/Np at low temperature.
