摘要
Hot neutron diffraction has been used to study the magnetic structure of GdCu6. Long range antiferromagnetic order with a propagation vector of (h 0 0) has been determined below the Neel temperature T-N = 16 K from the neutron powder refinement. The magnetic moments are oriented normal to the a direction, which is in agreement with previously reported results of bulk experiments. Mean field model calculations suggest that the magnetic structure is a helix.
