Regulating oxygen content and superconductivity in LaNiO
Peiyue Ma, Jingyuan Li, Xing Huang +17
The synthesis of high-quality Ruddlesden-Popper (RP) nickelates remains challenging due to variations in oxygen content and the prevalence of intergrown RP phases. Precisely contro…
Superconductivity in monolayer-trilayer phase of LaNiO under high pressure
Chaoxin Huang, Jingyuan Li, Xing Huang +7
The discovery of 80 K superconductivity in pressurized bilayer Ruddlesden-Popper (RP) nickelate LaNiO has established a new high-temperature superconductor family. The…
Doping dependence of the magnetic ground state in the frustrated magnets BaTeWO ( = Mn, Co)
Chaoxin Huang, Lisi Li, Peiyue Ma +3
Theoretically, the relative change of the Heisenberg-type nearest-neighbor coupling and next-nearest-neighbor coupling in the face-centered-cubic lattice can give rise…
Ground state and magnetic transitions of the orthorhombic antiferromagnet CaCoTeO
Xing Huang, Peiyue Ma, Mengwu Huo +8
We report the systematic synthesis, crystal structure, magnetization, and powder neutron diffraction of single crystalline and polycrystalline CaCoTeO samples. CaCoTeO$…
Identification of the superconductivity in bilayer nickelate LaNiO upon 100 GPa
Jingyuan Li, Di Peng, Peiyue Ma +14
Identification of superconductivity in the Ruddlesden-Popper phases of nickelates under high pressure remains challenging. Here, we report a comprehensive study of the crystal stru…
Low volume fraction of high-Tc superconductivity in La3Ni2O7 at 80 K and ambient pressure
Mengwu Huo, Peiyue Ma, Chaoxin Huang +3
The discovery of superconductivity in pressurized La3Ni2O7 with a transition temperature of approximately 80 K above the boiling point of liquid nitrogen has sparked significant at…
