Neutron diffraction study and theoretical analysis of the antiferromagnetic order and diffuse scattering in the layered Kagome system CaBaCoFeO
Johannes D. Reim, Erik Rosén, Oksana Zaharko +4
The hexagonal swedenborgite, CaBaCoFeO, is a chiral frustrated antiferromagnet, in which magnetic ions form alternating Kagome and triangular layers. We observe a long…
Competing Ferri- and Antiferromagnetic Phases in Geometrically Frustrated LuFe2O4
J. de Groot, K. Marty, M. D. Lumsden +12
We present a detailed study of magnetism in LuFe2O4, combining magnetization measurements with neutron and soft x-ray diffraction. The magnetic phase diagram in the vicinity of T_N…
Spin correlations in the extended kagome system YBaCo3FeO7
Martin Valldor, Raphaël P. Hermann, Joachim Wuttke +2
The transition metal based oxide YBaCo3FeO7 is structurally related to the mineral Swedenborgite SbNaBe4O7, a polar non-centrosymmetric crystal system. The magnetic Co3Fe sublattic…
XYZ-polarisation analysis of diffuse magnetic neutron scattering from single crystals
Werner Schweika
Studies of diffuse magnetic scattering largely benefit from the use of a multi-detector covering wide scattering angles. Therefore, the different contributions to the diffuse scatt…
Incommensurate Charge Order Phase in Fe2OBO3 due to Geometrical Frustration
M. Angst, R. P. Hermann, W. Schweika +7
The temperature dependence of charge order in Fe2OBO3 was investigated by resistivity and differential scanning calorimetry measurements, Mossbauer spectroscopy, and synchrotron x-…
Approaching the ground state of the kagome antiferromagnet
W. Schweika, M. Valldor, P. Lemmens
Y{0.5}$Ca{0.5}BaCo4O7 contains kagome layers of Co ions, whose spins are strongly coupled according to a Curie-Weiss temperature of -2200 K. At low temperatures, T = 1.2 K, our dif…
