(a) Experimental (crosses), calculated (line) and difference (noisy line below observed and calculated patterns) NPD profiles for Ba3(FeS4)Br at 4 K. Vertical bars indicate the calculated positions of Bragg peaks from the nuclear phase and from the magnetic phase (from the top). λ = 1.5398 Å. Rwp = 0.0558, Rp = 0.0450, χ2 = 1.742. Inset: Refinement with nuclear phase only. Some extra peaks from unknown impurities were excluded. (b) Temperature dependent intensities of the (010) magnetic reflection. (c) Magnetic structure of Ba3(FeS4)Br view down b axis (left) and c axis (right). Ba and Br atoms were omitted for clarity.
