Growth of layered LuFeO and LuFeO single crystals exhibiting long-range charge order via the optical floating-zone method
Sabreen Hammouda, Manuel Angst
We report the controlled growth of single crystals of intercalated layered LuFeO (=1,2) with different oxygen stoichiometries . For the fir…
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…
Ferroelectricity from iron valence ordering in rare earth ferrites?
Manuel Angst
The possibility of multiferroicity arising from charge ordering in LuFe2O4 and structurally related rare earth ferrites is reviewed. Recent experimental work on macroscopic indicat…
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…
Phonon Softening and Pressure-Induced Phase Transitions in Quartz Structured Compound, FePO4
R. Mittal, R. P. Hermann, M. Angst +5
Nuclear resonant inelastic x-ray scattering on quartz structured 57FePO4 as a function of pressure, up to 8 GPa reveals hardening of the low-energy phonons under applied pressures…
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…
