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…
The tetragonal-cubic transition of davemaoite: Implications for lower mantle seismic anomalies
Yoshiyuki Okuda, Bin Chen, Juliana Peckenpaugh +5
Davemaoite (CaSiO3 perovskite) is the third most abundant mineral in Earth's lower mantle and a dominant phase in subducted oceanic crust. Its crystal structure is distorted (tetra…
Low electrical conductivity of dry CaSiO3 perovskite under lower mantle conditions
Yoshiyuki Okuda, Bin Chen, Juliana Peckenpaugh +1
Electrical conductivity (EC) provides important constraints on the composition and volatile distribution of Earth's deep mantle, yet the EC of davemaoite (CaSiO3 perovskite), a maj…
