Tuning from Frustrated Magnetism to Superconductivity in Quasi-One-Dimensional KCrAs Through Hydrogen Doping
Keith M. Taddei, Liurukara D. Sanjeewa, Bing-Hua Lei +5
We report the charge doping of KCrAs via H intercalation. We show that the previously reported ethanol bath deintercalation of KCrAs to KCrAs has a seco…
Structural Instability and Magnetism of Superconducting KCrAs
Guangzong Xing, Ling Shang, Yuhao Fu +4
We find a lattice instability in the superconductor KCrAs, corresponding to a distortion of the Cr metallic wires in the crystal structure. This distortion couples strongly…
Frustrated structural instability in superconducting quasi-one-dimensional KCrAs
Keith M. Taddei, Guangzong Xing, Jifeng Sun +6
We present neutron total scattering and density functional theory studies on quasi-one-dimensional superconducting KCrAs revealing a frustrated structural instability.…
High-pressure Phase Stability and Superconductivity of Pnictogen Hydrides and Chemical Trends for Compressed Hydrides
Yuhao Fu, Xiangpo Du, Lijun Zhang +7
Binary hydrides formed by the pnictogens of phosphorus, arsenic and antimony are studied at high pressures using first principles methods. Stable structures are predicted and their…
