Figure 4
The Rietveld refinement pattern and the difference plot of the neutron diffraction pattern for MnO at T = 2 K (top), 100 K (middle) and 125 K (bottom) measured at HRPT with the wavelength λ = 1.886 Å. The lines are the refinement patterns for MSG Cc2/c below the Néel temperature for T = 100 K and paramagnetic SG for 125 K. 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. |
