Neutron diffraction study of the magnetic ordering in NpBi
Abstract
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 01‖, mk// k) below TN=192.5K. The ordered magnetic moment develops at TN with a critical exponent β=0.31±0.02 an increases continuosly on cooling to reach a value of 2.48μ B/Np at low temperature.
