The directional components of the magnetic moment along the x, y and z axes (Mx, My and Mz, respectively) in the approximate structures with c′ = 20/7 c of the basic structures for the magnetic models in P21/n.1′(0βγ)0ss, Pa.1′(00γ)0s, Pn.1′(0βγ)0ss and P21.1′(0βγ)0s at 0.12 GPa and 2 K. For the sake of clarity, the components are plotted only for five unit cells. Points indicate values realized on Cr sites, full lines show the underlying modulation function. The colours correspond to different Cr sites. Blue, red, green and yellow symbols/lines are for CrI (x, y, z), CrII (x + ½, −y + ½, −z + ½), CrIII (−x + ½, −y, z + ½) and CrIV (−x, y + ½, −z), respectively. The dashed grey lines mark the unit-cell borders of the basic crystal structure. The absolute values |M| of the magnetic moment are constant: |M| = 3.17 (3) μB for P21/n.1′(0βγ)0ss, |M| = 3.18 (2) μB for Pa.1′(00γ)0s, |M| = 3.59 (6) μB for Pn.1′(0βγ)0ss and |M| = 3.15 (2) μB for P21.1′(0βγ)0s. |
