Rietveld refinements of the neutron powder data (central wavelength of 2.665 Å) of Mn3Fe2Si3 in magnetic space group PCnan at (a) 90 K and (b) 20 K, and (c) in magnetic space group PC2221 at 20 K. Grey tick marks indicate the positions of nuclear and magnetic reflections. The difference curve is shown below. The insets present selected characteristic magnetic peaks in the 2–12.5 Å region. |
