Two distinct superconducting regimes in Ti4Co2O under pressures
Lifen Shi, Keyuan Ma, Binbin Ruan +8
We report on the pressure dependence of superconducting transition temperature Tc and upper critical field Bc2(0) through electrical transport of the Ti4Co2O superconductor (eg.,th…

New phase space of hardness materials and synergic enhancement of hardness and toughness in superconducting Ti2Co and Ti4Co2X (X = B, C, N, O)
Lifen Shi, Keyuan Ma, Jingyu Hou +12
Compared to traditional superhard materials with high electron density and strong covalent bonds, alloy materials mainly composed of metallic bonding structures typically have grea…

Chemical versus physical pressure effects on the structure transition of bilayer nickelates
Gang Wang, Ningning Wang, Tenglong Lu +11
The observation of high- superconductivity (HTSC) in concomitant with pressure-induced orthorhombic-tetragonal structural transition in the bilayer LaNiO has spa…
