Abstract

The Mn cation distribution in the seven sublattices of theW-type structure has been determined from high temperature neutron diffraction data of a SrMn2Fe16O27 powder sample. The Mn2+ ions enter the tetrahedral sites of blockS with a preference for site 4e. Mn3+ ions in small amounts are found in the octahedral sites, substituting for Fe3+, while 0.3 Fe2+ has been found in site 6g. The sample has the formula SrMn2.4Fe15.6O27. The crystal structure has been described in the non-centrosymmetric P¯62c space group, instead of the usual P63/mmc one. The magnetic structure, obtained from low temperature (4.2 K) data, is collinear, with the spins parallel to thec axis, according to the Gorter model. The magnetic moments of the sites give an experimental magnetization valueM s=28.4(1.5) μB/f.u., in good agreement with magnetic measurements and the theoretical value.
