Figure 3
The Rietveld refinement pattern and the difference plot of the neutron diffraction pattern for NiO at T = 2 K measured at HRPT with the wavelength λ = 1.886 Å. The lines are the refinement patterns based on the magnetic model [{R_{I}\bar{3}c}] (top) and Cc2/c (bottom) shown in Table 1[link]. The magnetic contributions are shown by the green lines. The rows of ticks show the Bragg peak positions for crystal (upper) and magnetic (lower) structures. The difference between the observed and calculated intensities is shown by the dotted blue line. Since both refinements are visually identical, we zoom the bottom Cc2/c figure to better show the magnetic contribution. The minor unindexed peaks are due to λ/2, as discussed in the text and illustrated in Fig. 8[link].
