High temperature transitions in Ruddlesden-Popper nickelates LaNiO
P. Reiss, A. Shevchenko, P. S. Lizama +9
The discovery of superconductivity at in the infinite-layer nickelate , followed by superconductivity at …
Unveiling orbital landscapes in strongly correlated bulk nickelates with -NIXS
Edgar Abarca Morales, Martin Sundermann, Brett Leedahl +10
We leverage -orbital non-resonant inelastic X-ray scattering (-NIXS) to perform orbital imaging on three bulk rare-earth nickelates spanning a range of formal nickel valence…
Imaging stripe dynamics in trilayer nickelate LaNiO
Uladzislau Mikhailau, Luke Rhodes, Siri A. Berge +5
Since the discovery of high-temperature superconductivity in nickelate superconductors, it is an open question how closely the superconducting state resembles that of cuprate super…
Gapped 1/9 Magnetization Plateau in the Anisotropic Kagome Antiferromagnet Y-kapellasite
Dipranjan Chatterjee, Paul A. Goddard, Ewan R. P. Thomas +11
Fractional magnetization plateaus provide a sensitive probe of many-body spin states in frustrated quantum magnets, yet their microscopic origin in kagome antiferromagnets remains…
Electronic excitations in the Shastry-Sutherland compound SrCu(BO)
Tariq Leinen, Ola K. Forslund, Eugenio Paris +13
SrCu2(BO3)2 (SCBO) is a paradigmatic realization of the Shastry-Sutherland model, hosting geometrically frustrated spin dimers and a variety of quantum magnetic phases and phenomen…
From Narrow-gap Semiconductor to Metallic Altermagnet: Optical Fingerprints of Co-Doped FeSb2
R. Mathew Roy, M. Povolotskiy, J. Kirschke +11
The realization of bulk metallic altermagnetism has remained elusive despite the growing number of candidate materials. Here, we present evidence that moderate cobalt substitution…
