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…

Electrical Conductivity of Superionic Hydrous SiO2 and the Origin of Lower-mantle High Conductivity Anomalies Beneath Subduction Zones
Mako Inada, Yoshiyuki Okuda, Kenta Oka +3
Electrical conductivity (EC) is one of the important physical properties of minerals and rocks that can be used to characterize the composition and structure of the deep interior o…

Pressure-induced volumetric negative thermal expansion in CoZr2 superconductor
Yuto Watanabe, Hiroto Arima, Saori Kawaguchi-Imada +10
We investigate the thermal expansion and superconducting properties of a CuAl2-type (tetragonal) superconductor CoZr2 under high pressures. We perform high-pressure synchrotron X-r…
