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
Metal-insulator transition in cuir2s4: xas results on the electronic structure
Mark Croft,Mark Croft,W. Caliebe,Hyungje Woo,Trevor A. Tyson,D. Sills,Yew San Hor,Sang-Wook Cheong,Valery Kiryukhin,Sejung Oh +9 more
TL;DR: In this article, the I-phase stabilization involves an interplay of charge and d-orbital orientation ordering along Ir chains, a quadrupling of the Ir-chain repeat unit, and correlated dimer spin-singlet formation.
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.
Journal ArticleDOI
First-Order Transition in the Itinerant Ferromagnet CoS 1.9 Se 0.1
TL;DR: In this article, the longwavelength spin excitations were found to be conventional ferromagnetic spin waves with negligible spin-wave gap, indicating that this system is also an excellent isotropic (soft) ferromagnet.
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: In this article, it was shown that the AB2X4 spinel structure of CuIr2S4 undergoes a simultaneous charge-ordering and spin-dimerization transition, a rare phenomenon in three-dimensional compounds.
