Site-selective observation of spin dynamics of a Tomonaga-Luttinger liquid in frustrated Heisenberg chains
Diep Minh Nguyen, Azimjon A. Temurjonov, Daigorou Hirai +6
Low-energy spin dynamics is investigated by Cl NMR measurements in a frustrated antiferromagnet CaReOCl. The local spin susceptibility measured with the Knight…
Topological Semimetal KAlGe with Novel Electronic Instability
Toshiya Ikenobe, Takahiro Yamada, Jun-ichi Yamaura +6
Compounds with the anti-PbFCl structure exhibit a variety of electronic instabilities and intriguing physical properties. NaAlSi and NaAlGe are similar topological nodal-line semim…
Successive phase transitions of the spin-orbit-coupled metal Cd2Re2O7 probed by high-resolution synchrotron x-ray diffraction
Daigorou Hirai, Atsuhito Fukui, Hajime Sagayama +2
The 5d pyrochlore oxide superconductor Cd2Re2O7 (CRO) has attracted significant interest as a spin-orbit-coupled metal (SOCM) that spontaneously undergoes a phase transition to an…
Fermi surface and light quasi particles in hourglass nodal chain metal \b{eta}-ReO2
Daigorou Hirai, Takahito Anbai, Takako Konoike +8
Quantum oscillations in magnetic torque and electrical resistivity were measured to investigate the electronic structure of \b{eta}-ReO2, a candidate hourglass nodal chain metal (D…
Linear Trimer Formation by Three-Center-Four-Electron Bonding in RuP
Daigorou Hirai, Keita Kojima, Naoyuki Katayama +3
In molecules like hydrogen, most chemical bonds are formed by sharing two electrons from each atom in the bonding molecular orbital (two-center-two-electron (2c2e) bonding). There…
Inelastic Neutron Scattering Study of the Spin Dynamics in the Breathing Pyrochlore System LiGa0.95In0.05Cr4O8
Yu Tanaka, Rafał Wawrzyńczak, Manh Duc Le +6
The A-site ordered chromate spinels LiGa1-xInxCr4O8 host a network of size-alternating spin-3/2 Cr3+ tetrahedra known as a 'breathing' pyrochlore lattice. For the x=0.05 compositio…
