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 $κ$ -(BEDT-TTF) $_{2}$ Cu[N(CN) $_{2}$ ]Cl, which is a candidate for an altermagnet. From…

Hybridization-gap Formation and Superconductivity in the Pressure-induced Semimetallic Phase of the Excitonic Insulator Ta $_{2}$ NiSe $_{5}$

Kazuyuki Matsubayashi, Hidekazu Okamura, Takashi Mizokawa +19

The excitonic insulator Ta $_{2}$ NiSe $_{5}$ 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 $f$ Electron States in YbCu $_{2}$ Ge $_{2}$ at High Pressures to 20 GPa

H. Okamura, M. Nagata, A. Tsubouchi +3

Optical conductivity [ $σ (ω)$ ] of YbCu $_{2}$ Ge $_{2}$ has been measured at external pressures ( $P$ ) to 20 GPa, to study the $P$ evolution of $f$ electron hybridized states. At $P$ =0, $σ(…

Spectroscopic signature of trimer Mott insulator and charge disproportionation in BaIrO $_{3}$

R. Okazaki, S. Ito, K. Tanabe +4

We have measured the reflectivity spectra of the barium iridate $9 R$ BaIrO $_{3}$ , the crystal structure of which consists of characteristic Ir $_{3}$ O $_{12}$ trimers. In the high-temper…

Dimer-Mott and charge-ordered insulating states in the quasi-one-dimensional organic conductors $δ_{P}^{'}$ - and $δ_{C}^{'}$ -(BPDT-TTF) $_{2}$ ICl $_{2}$

R. Kobayashi, K. Hashimoto, N. Yoneyama +7

We investigated the electronic states of the quasi-one-dimensional organic conductors $δ_{P}^{'}$ -(BPDT-TTF) $_{2}$ ICl $_{2}$ and $δ_{C}^{'}$ -(BPDT-TTF) $_{2}$ ICl $_{2}$ , both of which are insulatin…
