Collective spin excitations in trilayer nickelate LaNiO
Ying Chan, Yuehong Li, Yujie Yan +14
Ruddlesden-Popper (RP) nickelates have recently emerged as a new family of high-temperature superconductors. In bilayer RP nickelates, magnetic excitations with large exchange coup…
Contrasting Momentum-Selective Spin-Density-Wave Gaps in Bilayer and Trilayer Nickelates
Jun Shu, Jun Shen, Xiaoxiang Zhou +12
Resolving where the density-wave gap opens in momentum space is essential for identifying the microscopic origin of the instability in layered nickelates. Using polarization-resolv…
