Observation of complex orbital order in MnV2O4
Chihaya Koyama, Shunsuke Kitou, Taishun Manjo +8
Orbital ordering in vanadium spinel oxides with a geometrically frustrated pyrochlore structure has been a subject of controversy, owing to competing theoretical models and the abs…
Coupled structural and electronic evolution under pressure in CuIr2Se4, CuRh2S4, and CuRh2Se4
M. Emi, M. Shiomi, K. Kojima +15
Spinel chalcogenides provide a platform for investigating the interplay among metallic, superconducting, and pressure-induced insulating states. Here, we combine synchrotron powder…
Real-space determination of orbital states driving successive phase transitions in FeV2O4
Chihaya Koyama, Yusuke Nomura, Shunsuke Kitou +8
Direct experimental access to orbital states in strongly correlated materials remains a major challenge, despite their central role in driving coupled structural and magnetic phase…
Superconductivity in High-Entropy Antimonide MPtSb (M = equimolar Ru, Rh, Pd, and Ir)
Daigorou Hirai, Naoto Uematsu, Koh Saitoh +2
The high-entropy concept was applied to the synthesis of transition-metal antimonides, M1-xPtxSb (M = equimolar Ru, Rh, Pd, and Ir). High-entropy antimonide samples crystallized in…
Odd-parity multipole order in the spin-orbit coupled metallic pyrochlore PbReO
Yuki Nakayama, Daigorou Hirai, Hajime Sagayama +6
The pyrochlore oxide Pb2Re2O7-δ (PRO) is a candidate spin-orbit-coupled metal (SOCM) that exhibits a structural phase transition with inversion symmetry breaking. In this study, we…
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…
