Real-Space Observation of Ligand Hole State in Cubic Perovskite SrFeO
Shunsuke Kitou, Masaki Gen, Yuiga Nakamura +4
An anomalously high valence state sometimes shows up in transition-metal oxide compounds. In such systems, holes tend to occupy mainly the ligand orbitals, giving rise to inter…
Quantum Oscillations of Electrical Resistivity in an Insulator
Z. Xiang, Y. Kasahara, T. Asaba +13
In metals, orbital motions of conduction electrons on the Fermi surface are quantized in magnetic fields, which is manifested by quantum oscillations in electrical resistivity. Thi…
Large entropy change derived from the orbitally assisted three-centered two-electron σ bond formation in a metallic Li0.33VS2
N. Katayama, S. Tamura, T. Yamaguchi +8
We discuss herein the emergence of a large entropy change in metallic Li0.33VS2 derived from the orbitally assisted loose σ bond formation. Comprehensive structural studies based o…
Ferromagnetic Peierls insulator state in MgMnO ( = K, Rb, Cs)
T. Yamaguchi, K. Sugimoto, Y. Ohta +2
Using the density-functional-theory based electronic structure calculations, we study the electronic state of recently discovered mixed-valent manganese oxides MgMnO$_{1…
First-Order Structural Change Accompanied by Yb Valence Transition in YbInCu4
Satoshi Tsutsui, Kunihisa Sugimoto, Ryoma Tsunoda +4
A diffraction experiment using a high energy x-ray was carried out on YbInCu4. Below the Yb valence transition temperature, the splitting of Bragg peaks was detected in higher-orde…
Direct observation of lattice symmetry breaking at the hidden-order transition in URu2Si2
S. Tonegawa, S. Kasahara, T. Fukuda +12
Since the 1985 discovery of the phase transition at K in the heavy-fermion metal URuSi, neither symmetry change in the crystal structure nor magnetic orde…
Switching of Conducting Planes by Partial Dimer Formation in IrTe
Tatsuya Toriyama, Masao Kobori, Takehisa Konishi +7
Single-crystal X-ray diffraction was employed to study the structural-electronic phase transition of IrTe at approximately 270 K. The low-temperature structure was found to be…
Non-complicated EuTiO3 Structure
David S. Ellis, Hiroshi Uchiyama, Satoshi Tsutsui +3
A recently published paper [arXiv:1206.5417 ]showed strong incommensurate diffraction peaks in EuTiO3 around zone boundary R-points. We wish to convey that in our samples, and, it…
Phonon Softening and Dispersion in EuTiO3
David S. Ellis, Hiroshi Uchiyama, Satoshi Tsutsui +4
We measured phonon dispersion in single crystal EuTiO using inelastic x-ray scattering. A structural transition to an antiferrodistortive phase was found at a critical temperat…
Nematic and meta-nematic transitions in the iron pnictides
S. Kasahara, H. J. Shi, K. Hashimoto +8
Strongly interacting electrons can exhibit novel collective phases, among which the electronic nematic phases are perhaps the most surprising as they spontaneously break rotational…
Resonant X-Ray Diffraction Study of Strongly Spin-Orbit-Coupled Mott Insulator CaIrO3
Kenya Ohgushi, Jun-ichi Yamaura, Hiroyuki Ohsumi +6
We performed resonant x-ray diffraction experiments at the absorption edges for the post-perovskite-type compound CaIrO with electronic configuration. By obs…
Epitaxially stabilized iridium spinel oxide without cations in the tetrahedral site
Hiromichi Kuriyama, Jobu Matsuno, Seiji Niitaka +7
Single-crystalline thin film of an iridium dioxide polymorph Ir2O4 has been fabricated by the pulsed laser deposition of LixIr2O4 precursor and the subsequent Li-deintercalation us…
