(a) The temperature dependence of the 002 and reflections in single-crystal neutron diffraction. (b) The diffraction signals of 00l (l = 2n + 1) and 006 at 2 K. (c) The refinement results of the magnetic structure with the atomic structure at 2 K. (d) The magnetic structure refinement result with the space group P63/mm′c′. The magnetic moment of Fei is larger than that of Feii. |
