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…
Colossal Positive Magnetoresistance in a Doped Nearly Magnetic Semiconductor
Rongwei Hu, K. J. Thomas, Y. Lee +9
We report on a positive colossal magnetoresistance (MR) induced by metallization of FeSb, a nearly magnetic or "Kondo" semiconductor with 3d ions. We discuss contribution of…
