Journal ArticleDOI
Formation of isomorphic Ir3+ and Ir4+ octamers and spin dimerization in the spinel CuIr2S4.
Paolo G. Radaelli,Yoichi Horibe,Yoichi Horibe,Yoichi Horibe,Matthias J. Gutmann,Hiroki Ishibashi,Hiroki Ishibashi,Cheng-Hsuan Chen,Richard M. Ibberson,Yasumasa Koyama,Yew San Hor,Valery Kiryukhin,Sang-Wook Cheong +12 more
TL;DR: The results indicate that CuIr2S4 undergoes a simultaneous charge-ordering and spin-dimerization transition—a rare phenomenon in three-dimensional compounds.
Journal ArticleDOI
Exchange interaction effects on the optical properties of LuMnO3.
A. B. Souchkov,Jeffrey R. Simpson,M. Quijada,Hiroki Ishibashi,Namjung Hur,J. S. Ahn,J. S. Ahn,Sang-Wook Cheong,Andrew J. Millis,H. D. Drew +9 more
TL;DR: In this article, the optical conductivity of LuMnO3 was measured at temperatures between 4 and 300 K, and it was shown that a symmetry allowed on-site Mn d-d transition near 1.7 eV is observed to blueshift (approximately 0.1 eV) in the antiferromagnetic state due to Mn-Mn superexchange interactions.
Journal ArticleDOI
Ferroelectricity driven by Y d0-ness with rehybridization in YMnO3.
Deok-Yong Cho,J.-Y. Kim,Byeong-Gyu Park,K.-J. Rho,Jae-Hoon Park,H. J. Noh,Beom Jun Kim,Se-Jung Oh,H. M. Park,J. S. Ahn,Hiroki Ishibashi,Sang-Wook Cheong,J. H. Lee,Pattukkannu Murugavel,Tae-Hee Noh,Arata Tanaka,Takeo Jo +16 more
TL;DR: In this article, the authors investigated the electronic structure of hexagonal multiferroic YMnO3 using the polarization dependent x-ray absorption spectroscopy (XAS) at O K and Mn L(2,3) edges.

Journal ArticleDOI
X-ray-Induced Disordering of the Dimerization Pattern and Apparent Low-Temperature Enhancement of Lattice Symmetry in Spinel CuIr 2 S 4
Hiroki Ishibashi,Hiroki Ishibashi,T. Y. Koo,Yew San Hor,Alexander V. Borissov,Paolo G. Radaelli,Paolo G. Radaelli,Yoichi Horibe,Yoichi Horibe,Sang-Wook Cheong,Sang-Wook Cheong,Valery Kiryukhin +11 more
TL;DR: In this article, it was shown that x-ray irradiation disorders the lattice dimerization pattern, producing a state in which the orientation of the dimers is preserved, but the translational long-range order is destroyed.
