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…
Evolution of the superconductivity in pressurized La3-xSmxNi2O7
Qingyi Zhong, Junfeng Chen, Zhengyang Qiu +7
Motivated by the discovery of superconductivity in bilayer LaNiO at 80 K and the increased superconducting transition temperature, , up to 92 K in single cr…
Interlayer coupling enhanced superconductivity near 100 K in LaNdNiO
Zhengyang Qiu, Junfeng Chen, Dmitrii V. Semenok +12
Systematically controlling the superconducting transition temperature () in the bilayer Ruddlesden-Popper nickelate LaNiO remains a significant challenge. H…
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…
