Magnetic Ni-N-Ni Centers in N-substituted NiO
Simon Godin, Ilya S. Elfimov, Fengmiao Li +6
To explore how anion substitution modifies the existing magnetism in strongly correlated oxides, we investigate local electronic states and magnetic ordering in nickel oxide (NiO)…
Impact of synthesis method on the structure and function of high entropy oxides
Mario U. González-Rivas, Solveig S. Aamlid, Megan R. Rutherford +9
The term sample dependence describes the troublesome tendency of nominally equivalent samples to exhibit different physical properties. High entropy oxides (HEOs) are a class of ma…
Superconductivity in the parent infinite-layer nickelate NdNiO
C. T. Parzyck, Y. Wu, L. Bhatt +14
We report evidence for superconductivity with onset temperatures up to 11 K in thin films of the infinite-layer nickelate parent compound NdNiO. A combination of oxide molecula…
Resolving the Electronic Ground State of La3Ni2O7-δ Films
Xiaolin Ren, Ronny Sutarto, Xianxin Wu +7
The recent discovery of a superconductivity signature in La3Ni2O7-δ under a pressure of 14 GPa, with a superconducting transition temperature of around 80 K, has attracted consider…
Signatures of polarized chiral spin disproportionation in rare earth nickelates
Jiarui Li, Robert J. Green, Claribel Domínguez +12
In rare earth nickelates (RENiO), electron-lattice coupling drives a concurrent metal-to-insulator and bond disproportionation phase transition whose microscopic origin has lon…
Anisotropic Spin Stripe Domains in Bilayer LaNiO
N. K Gupta, R. Gong, Y. Wu +10
The discovery of superconductivity in LaNiO under pressure has motivated the investigation of a parent spin density wave (SDW) state, which could provide the underlying…
