orbital delocalization and magnetic collapse in superconducting (La,Pr)NiO films
Xiaoyang Chen, Wenliang Zhang, Fei Peng +20
The recent discovery of Ruddlesden--Popper (RP) nickelate thin-film superconductors has opened a new frontier in unconventional superconductivity. Its realization requires both com…
Unusual strain relaxation and Dirac semimetallic behavior in epitaxial antiperovskite nitrides
Ting Cui, Zihan Xu, Qinghua Zhang +13
Antiperovskite nitrides (X3AN) are the structural analogues to perovskite oxides, while their epitaxial growth and electronic properties remain largely unexplored. We report the su…
Observation of square-like moire lattice and quasicrystalline order in twisted rock-salt nitrides
Dongke Rong, Qinghua Zhang, Ting Cui +10
Twistronics, which exploits moire modulation of lattice and electronic structures in twisted bilayers, has emerged as a powerful approach to engineer novel quantum states. Recent e…
Advancing Antiferromagnetic Nitrides via Metal Alloy Nitridation
Qianying Wang, Zexu He, Lele Zhang +14
Nitride materials, valued for their structural stability and exceptional physical properties, have garnered significant interest in both fundamental research and technological appl…
Designing Optimal Distorted-Octahedra Superlattices for Strong Topological Hall Effect
Yiyan Fan, Qinghua Zhang, Jingdi Lu +11
Topologically protected spin states hold great promise for applications in next generation of memory circuits and spintronic devices. These intriguing textures typically emerge in…
Deteriorated Interlayer Coupling in Twisted Bilayer Cobaltites
Dongke Rong, Xiuqi Chen, Shengru Chen +15
A wealth of remarkable behaviors is observed at the interfaces between magnetic oxides due to the coexistence of Coulomb repulsion and interatomic exchange interactions. While prev…
