Persistent structural distortions and absent superconductivity in trilayer nickelate thin films
Abigail Y. Jiang, Maria Bambrick-Santoyo, Lopa Bhatt +14
A new family of high-temperature superconductors was recently discovered in the Ruddlesden-Popper nickelates, where superconductivity emerges concomitant with suppression o…
Probing La-based nickelates with Ni 1 core-level photoelectron spectroscopy
Daisuke Takegami, Naoki Ito, Koto Fujinuma +15
We present a comparative Ni core level photoemission study of LaNiO, NdNiO, and LaNiO using both the Ni and the Ni . We address the challenges…
Observation of microscopic domain effects in the metal-insulator transition of thin-film NdNiO
Lucy S. Nathwani, Anne Ruperto, Ashvini Vallipuram +8
Perovskite oxides display correlated electrical, magnetic, and thermal properties that can be further tuned in the thin-film limit, making them contenders for next-generation elect…
Superconducting phase diagram of multi-layer square-planar nickelates
Grace A. Pan, Dan Ferenc Segedin, Sophia F. R. TenHuisen +21
The discovery of superconductivity in square-planar nickelates has offered a rich materials platform to explore the origins of cuprate-like superconductivity. Experimental investig…
Topotactic oxidation of Ruddlesden-Popper nickelates reveals new structural family: oxygen-intercalated layered perovskites
Dan Ferenc Segedin, Jinkwon Kim, Harrison LaBollita +20
Layered perovskites such as the Dion-Jacobson, Ruddlesden-Popper, and Aurivillius families host a wide range of correlated electron phenomena, from high-temperature superconductivi…
Unconventional polaronic ground state in superconducting LiTiO
Zubia Hasan, Grace A. Pan, Harrison LaBollita +23
Geometrically frustrated lattices can display a range of correlated phenomena, ranging from spin frustration and charge order to dispersionless flat bands due to quantum interferen…
