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…

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…
