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…
Electronic Energy Scales of Cr ( = Cl, Br, and I) using High-resolution X-ray Scattering
Chamini S. Pathiraja, Jayajeewana N. Ranhili, Deniz Wong +7
Chromium tri-halides Cr ( = Cl, Br, and I) have recently become a focal point of research due to their intriguing low-temperature,layer-dependent magnetism that can be mani…
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…
Persistent paramagnons in high-temperature infinite-layer nickelate superconductors
Yujie Yan, Ying Chan, Xunyang Hong +26
The recent discovery of high-temperature superconductivity in hole-doped SmNiO, exhibiting the record-high transition temperature among infinite-layer (IL) nickelates, ha…
