Origin of the structural and magnetic anomalies of the layered compound SrFeO2: A density functional investigation

PHYSICAL REVIEW LETTERS, 100(16).

By: H. Xiang*, S. Wei * & M. Whangbo n

Charge order and the origin of giant magnetocapacitance in LuFe2O4

PHYSICAL REVIEW LETTERS, 98(24).

By: H. Xiang n & M. Whangbo n

TL;DR: The giant magnetocapacitance effect of LuFe(2)O(4) at room temperature is accounted for in terms of charge fluctuations arising from the interconversion between the two types of charge order, that becomes hindered by an applied magnetic field. (via Semantic Scholar)

Charge order superstructure with integer iron valence in Fe2OBO3

PHYSICAL REVIEW LETTERS, 99(8).

By: M. Angst *, P. Khalifah *, R. Hermann *, H. Xiang n, M. Whangbo n, V. Varadarajan*, J. Brill *, B. Sales *, D. Mandrus*

MeSH headings : Iron / chemistry; Spectroscopy, Mossbauer; X-Ray Diffraction
TL;DR: Bond-valence-sum analysis indicates integer valence states of the Fe ions in the charge ordered phase, suggesting Fe(2)OBO(3) is the clearest example of ionic charge order so far. (via Semantic Scholar)

2007 journal article

Density-functional characterization of the multiferroicity in spin spiral chain cuprates

PHYSICAL REVIEW LETTERS, 99(25).

By: H. Xiang n & M. Whangbo n

TL;DR: The ferroelectricity of the spiral magnets LiCu2O2 and LiCuVO4 was examined by calculating the electric polarizations of their spin spiral states on the basis of density-functional theory with spin-orbit coupling, and it is unambiguously revealed that spin- orbit coupling is responsible for the ferro electricity with the primary contribution from the spin- Orbit coupling on the Cu sites, but the asymmetric density distributionresponsible for the electric polarization occurs mainly around the O atoms.

Incommensurate charge order phase in Fe2OBO3 due to geometrical frustration

PHYSICAL REVIEW LETTERS, 99(25).

By: M. Angst *, R. Hermann *, W. Schweika *, J. Kim *, P. Khalifah *, H. Xiang n, M. Whangbo n, D. Kim *, B. Sales *, D. Mandrus *

TL;DR: The temperature dependence of charge order in Fe2OBO3 was investigated by resistivity and differential scanning calorimetry measurements, Mössbauer spectroscopy, and synchrotron x-ray scattering, revealing an intermediate phase between room temperature and 340 K, characterized by coexisting mobile and immobile carriers and by incommensurate superstructure modulations with temperature-dependent propagation vector.
