Anomalous Compressibility and Electronic Robustness of Metallic Delafossite PdCoO under Pressure
Cheng Peng, Pahuni Jain, Tyler Harper +2
The layered delafossite PdCoO is an exceptional oxide metal whose ultrahigh conductivity arises from a Pd-derived nearly-free-electron band. Here, high-pressure single-crystal…
Extending the La Solubility Limit in SrIrO through High-Pressure High-Temperature Synthesis
Cheng Peng, Weiwei Xie
La-doped bilayer iridates provide an important platform for studying the evolution of the spin-orbit-assisted Mott state under electron doping, but the La solubility achieved by co…
Site Preferences and "Coloring Problem" in Cu-doped BiMnO Quadruple Perovskite
Cheng Peng, Mingyu Xu, Yang Zhang +3
Lightly Cu-doped BiMnO (x = 0.05, 0.10, and 0.15) was investigated using high-pressure synthesis, single-crystal X-ray diffraction, pair distribution function (PDF) anal…
Superconductivity in the high-pressure tetragonal phase of UTe2
Yuhang Deng, Gabriel Mee, Tyler Wannamaker +4
Electrical transport and magnetic measurements have been made on UTe2 under pressure P up to approximately 16 GPa to determine the superconducting transition temperature Tc vs P ph…
Compressibility and High-Pressure Structure of CaMgBi and YbMgBi
Mario Calderón-Cueva, Allison Pease, Cheng Peng +5
Compounds with the formula in the CaAlSi structure type have garnered increasing interest across various solid-state research domains, such as quantum topological…
Impact of Cu-Mn ratio on Structure and Defects in Layered Multiferroic Cu1-xMn1+ySiTe3
Sai Venkata Gayathri Ayyagari, Boyang Zheng, Sreekant Anil +10
Multiferroic materials exhibit the coexistence of magnetic and ferroelectric order, enabling control of magnetism through electric fields and vice versa. These properties make them…
