(a) Magnetic structure refinement of neutron magnetic scattering of (Mo2/3Ho1/3)2GaC at 3 K. Observed intensity (black), calculated (red) and difference (blue). Magnetic satellite Bragg positions are indicated by purple vertical dashes. The red star symbols indicate the positions of the magnetic peaks of the HoGa3 impurity, which is ordered below 8 K. Inset: zoom of the low-angle part (15–22°) of the refinement. Note that the reflection indices are given in the parent phase basis (Cmcm). (b) Schematic of the incommensurate amplitude-modulated structure at 3 K (Cmcm unit-cell axes). Only one plane of Ho magnetic cations is shown for clarity.
