Heterostructuring as Gateway to Electron Doping of Nickelate Superconductors
Chao Deng, Motoharu Kitatani, Guiwen Jiang +7
Despite enormous expenditures in the research field, the electron-doped side of nickelate superconductors remains uncharted territory. Substituting the trivalent rare-earth cations…
Interface Spin-orbit Coupling Induced Room-temperature Ferromagnetic Insulator
Yuhao Hong, Shilin Hu, Ziyue Shen +10
Fabricating room-temperature ferromagnetic insulators, which are crucial candidates for next-generation dissipation-free quantum and spintronic devices, remains a significant chall…
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…
Lattice dynamics of the infinite-layer nickelate LaNiO
Shohei Hayashida, Vignesh Sundaramurthy, Wenfeng Wu +8
Infinite-layer (IL) nickelates have rapidly emerged as a new class of superconductors. However, due to the technical challenges of their topotactic synthesis, they have so far been…
Ultrahigh room-temperature hole conductivity in a perovskite cuprate with vanishing electron-correlation
Meng Wang, Jianbing Zhang, Liang Si +19
Electron-correlated two-dimensional (2D) cuprates have been extensively studied since the discovery of high-Tc superconductivity, in contrast, the three-dimensional (3D) counterpar…
Ultrahigh-temperature ferromagnetism in ultrathin insulating films with ripple-infinite-layer structure
Yazhuo Yi, Haoliang Huang, Ruiwen Shao +15
Ferromagnetism and electrical insulation are often at odds, signifying an inherent trade off. The simultaneous optimization of both in one material, essential for advancing spintro…
