Magneto-optical spectra of an organic antiferromagnet as a candidate for an altermagnet
Satoshi Iguchi, Hiroki Kobayashi, Yuka Ikemoto +5
We have measured the magneto-optical Kerr effect (MOKE) in an orthorhombic organic antiferromagnet -(BEDT-TTF)Cu[N(CN)]Cl, which is a candidate for an altermagnet. From…
Pressure suppression of the excitonic insulator state in Ta2NiSe5 observed by optical conductivity
H. Okamura, T. Mizokawa, K. Miki +9
The layered chalcogenide Ta2NiSe5 has recently attracted much interest as a strong candidate for the long sought excitonic insulator (EI). Since the physical properties of an EI ar…
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…
Optical Conductivity Study of Electron States in YbCuGe at High Pressures to 20 GPa
H. Okamura, M. Nagata, A. Tsubouchi +3
Optical conductivity [] of YbCuGe has been measured at external pressures () to 20 GPa, to study the evolution of electron hybridized states. At =0, $σ(…
Spectroscopic signature of trimer Mott insulator and charge disproportionation in BaIrO
R. Okazaki, S. Ito, K. Tanabe +4
We have measured the reflectivity spectra of the barium iridate BaIrO, the crystal structure of which consists of characteristic IrO trimers. In the high-temper…
Dimer-Mott and charge-ordered insulating states in the quasi-one-dimensional organic conductors - and -(BPDT-TTF)ICl
R. Kobayashi, K. Hashimoto, N. Yoneyama +7
We investigated the electronic states of the quasi-one-dimensional organic conductors -(BPDT-TTF)ICl and -(BPDT-TTF)ICl, both of which are insulatin…
