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…

Possibility of ferro-octupolar order in BaCaOsO assessed by X-ray magnetic dichroism measurements
Goro Shibata, Naomi Kawamura, Jun Okamoto +9
Localized electrons in a cubic crystal field possess multipoles such as electric quadrupoles and magnetic octupoles. We studied the cubic double perovskite BaCaOsO c…

Enhanced Superconductivity and Mixed-dimensional Behaviour in Infinite-layer Samarium Nickelate Thin Films
Mingwei Yang, Heng Wang, Jiayin Tang +24
Rare-earth infinite-layer nickelates represent an emerging class of unconventional superconductors, with materials synthesis largely limited to early lanthanide compounds. Here, we…
