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…

The Evolution of Magnetism in a Thin Film Pyrochlore Ferromagnetic Insulator

Margaret A. Anderson, Megan E. Goh, Yang Zhang +19

The pyrochlore vanadates are compelling candidates for next-generation dissipationless devices. Lu2V2O7 and Y2V2O7 are ferromagnetic insulators (Tc ~ 70 K) that are believed to exh…

Electronic band structure of a superconducting nickelate probed by the Seebeck coefficient in the disordered limit

G. Grissonnanche, G. A. Pan, H. LaBollita +9

Superconducting nickelates are a new family of strongly correlated electron materials with a phase diagram closely resembling that of superconducting cuprates. While analogy with t…
