Stoichiometric YFe2O4-δ single crystals grown by the optical floating zone method
Thomas Mueller, Joost de Groot, Joerg Strempfer +1
We report the growth of YFe2O4-δ single crystals by the optical floating zone method, showing for the first time the same magnetization as highly stoichiometric (δ= 0.00) powder sa…
Dielectric properties of charge ordered LuFe2O4 revisited: The apparent influence of contacts
Daniel Niermann, Florian Waschkowski, Joost de Groot +2
We show results of broadband dielectric measurements on the charge ordered, proposed to be mul- tiferroic material LuFe2O4. The temperature and frequency dependence of the complex…
Charge order in LuFe2O4: an unlikely route to ferroelectricity
J. de Groot, T. Mueller, R. A. Rosenberg +4
We present the refinement of the crystal structure of charge-ordered LuFe2O4, based on single-crystal x-ray diffraction data. The arrangement of the different Fe-valence states, de…
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…
