Excitonic dispersion of the intermediate-spin state in LaCoO revealed by resonant inelastic X-ray scattering
Ru-Pan Wang, Atsushi Hariki, Andrii Sotnikov +9
More than 50 years ago the electron-hole attraction was proposed to drive narrow gap semiconductors or semimetals to a new phase, the excitonic insulator. The experimental proof of…
Anisotropy in the thermal hysteresis of resistivity and charge density wave nature of single crystal SrFeO3-delta: X-ray absorption and photoemission studies
S. H. Hsieh, R. S. Solanki, Y. F. Wang +16
The local electronic and atomic structures of the high-quality single crystal of SrFeO3-{delta} ({delta}~0.19) were studied using temperature-dependent x-ray absorption and valence…
Elucidation of the helical spin structure of FeAs
T. Frawley, R. Schoonmaker, S. H. Lee +7
We present the results of resonant x-ray scattering measurements and electronic structure calculations on the monoarsenide FeAs. We elucidate details of the magnetic structure, sho…
Inverse Melting of an Electronic Liquid Crystal
Shu-Han Lee, Yen-Chung Lai, Chao-Hung Du +6
Inverse melting refers to the rare thermodynamic phenomenon in which a solid melts into a liquid upon cooling, a transition that can occur only when the ordered (solid) phase has m…
Magnetically induced electric polarization reversal in multiferroic TbMnO: Terbium spin reorientation studied by resonant x-ray diffraction
R. D. Johnson, C. Mazzoli, S. R. Bland +2
In multiferroic TbMnO, the behavior of the terbium ions forms a crucial part of the magneto-electric coupling. The result is a magnetically induced reversal of the electric…
Determination of magnetic order of the rare-earth ions in multiferroic TbMn2O5
R. D. Johnson, S. R. Bland, C. Mazzoli +5
We have employed resonant x-ray magnetic scattering to specifically probe the magnetic order of the rare-earth ions in multiferroic . Two energy resonances were…
