Entropy stabilization and effect of A-site ionic size in bilayer nickelates
Jia-Yi Lu, Jia-Xin Li, Xin-Yu Zhao +5
The discovery of high-temperature superconductivity in LaNiO under high pressure has sparked a surge of research into Ruddlesden-Popper (RP) nickelates. Currently, stab…
Stabilization of Tetragonal Phase and Aluminum-Doping Effect in a Bilayer Nickelate
Jia-Yi Lu, Yi-Qiang Lin, Kai-Xin Ye +7
Recent studies suggest that the tetragonal phase of the Ruddlesden-Popper (RP) bilayer nickelate, LaNiO or LaPrNiO, which is stabilized under high pressures…
Quantum Criticality by Interaction Frustration in a Square-Planar Lattice
Yi-Qiang Lin, Chang-Chao Liu, Jia-Xin Li +16
We report experimental and theoretical investigations on ThCrGeC, a metallic compound in which CrC planes form a square-planar lattice. Neutron powder diffraction, magn…
Discovery of an Antiferromagnetic Topological Nodal-line Kondo Semimetal
D. F. Liu, Y. F. Xu, H. Y. Hu +34
The symbiosis of strong interactions, flat bands, topology and symmetry has led to the discovery of exotic phases of matter, including fractional Chern insulators, correlated moirÃ…
