Hybridization-gap Formation and Superconductivity in the Pressure-induced Semimetallic Phase of the Excitonic Insulator TaNiSe
Kazuyuki Matsubayashi, Hidekazu Okamura, Takashi Mizokawa +19
The excitonic insulator TaNiSe experiences a first-order structural transition under pressure from rippled to flat layer-structure at Ps = 3 GPa, which drives the system fr…
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…
Peierls Mechanism of the Metal-Insulator Transition in Ferromagnetic Hollandite K2Cr8O16
T. Toriyama, A. Nakao, Y. Yamaki +10
Synchrotron X-ray diffraction experiment shows that the metal-insulator transition occurring in a ferromagnetic state of a hollandite KCrO is accompanied by a struct…
KCrO predicted as a half-metallic ferromagnet: Scenario for a metal-insulator transition
M. Sakamaki, T. Konishi, Y. Ohta
Based on the first-principles electronic structure calculations, we predict that a chromium oxide KCrO of hollandite type should be a half-metallic ferromagnet where…
Ab initio electronic structure calculation of hollandite vanadate KVO
M. Sakamaki, S. Horiuchi, T. Konishi +1
An \textit{ab initio} electronic structure calculation based on the generalized gradient approximation in the density functional theory is carried out to study the basic electronic…
Electronic structure of the strongly hybridized ferromagnet CeFe2
T. Konishi, K. Morikawa, K. Kobayashi +8
We report on results from high-energy spectroscopic measurements on CeFe2, a system of particular interest due to its anomalous ferromagnetism with an unusually low Curie temperatu…
