Charge order, dynamics, and magneto-structural transition in multiferroic LuFeO
X. S. Xu, M. Angst, T. V. Brinzari +8
We investigated the series of temperature and field-driven transitions in LuFeO by optical and Mössbauer spectroscopies, magnetization, and x-ray scattering in order to und…
Charge order in LuFe2O4: antiferroelectric ground state and coupling to magnetism
M. Angst, R. P. Hermann, A. D. Christianson +10
X-ray scattering by multiferroic LuFe2O4 is reported. Below 320 K, superstructure reflections indicate an incommensurate charge order with propagation close to (1/3,1/3,3/2). The c…
Weak Ferromagnetism in Fe1-xCoxSb2
Rongwei Hu, R. P. Hermann, F. Grandjean +4
Weak ferromagnetism in Fe1-xCoxSb2 is studied by magnetization and Mossbauer measurements. A small spontaneous magnetic moment of the order of 10^-3 uB appears along the b-axis for…
Charge Order Superstructure with Integer Iron Valence in Fe2OBO3
M. Angst, P. Khalifah, R. P. Hermann +6
Solution-grown single crystals of Fe2OBO3 were characterized by specific heat, Mossbauer spectroscopy, and x-ray diffraction. A peak in the specific heat at 340 K indicates the ons…
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-…
