Neutron diffraction data of the perovskite-type Mn₂O₃. a, b Rietveld refinement of the WISH neutron diffraction patterns collected at 60 K and 1.5 K, respectively. The black cross symbols and red solid lines represent the experimental and calculated intensities, respectively. The blue lines at the bottom of both plots are the difference between the experimental and calculated intensities. There are three sets of tick marks: the upper one indicates the positions of Bragg peaks for the nuclear, the middle one shows a few reflections of the vanadium can for the sample, and the lower one indicates the positions of Bragg peaks for magnetic scattering. The inset in a shows temperature dependence of the k_z-component of the magnetic propagation vector k₀. The inset in b shows magnified portion of the diffraction pattern where a satellite of the k_2± propagation vector is observed
