“…The reason for this inconsistency is probably the exact oxygen content of the individual samples. By introducing Ca at the Y site, thus changing also the average oxidation state of Co, diffuse neutron scattering was reported for partial replacement [38,39], and a structural transition with longrange magnetic ordering was observed for the composition CaBaCo 4 O 7 [40]. When replacing Co in YBaCo 4 O 7 , a manifold of magnetic ground states has been reported: a spin-liquid in YBaCo 3 FeO 7 [11], a mixture of long-and short-range ordering in CaBaCo 2 Fe 2 O 7 [13], and further.…”

We present a study combining neutron diffraction and 57 Fe Mössbauer spectroscopy on a powder sample of CaBaMn 2 Fe 2 O 7 belonging to the large family of swedenborgite compounds. The undistorted hexagonal crystal structure (space group P6 3 mc) is preserved down to low temperatures, and all employed techniques reveal a transition into a magnetically long-range ordered phase at T N = 205 K. The magnetic Bragg peak intensities from the powder diffraction patterns together with a symmetry analysis of the employed models unambiguously reveal the classical √ 3 × √ 3 magnetic structure on a hexagonal lattice with propagation vector q = ( 1 3 1 3 0). The nuclear Bragg peak intensities allowed the statistical distribution of Fe and Mn ions on both trigonal and kagome sites of the complex swedenborgite structure to be analyzed which was considered to explain the complex shape of the Mössbauer spectra.
