Structural stability, electronic structure, and magnetism of the double infinite-layer LaNiOF under chemical pressure and epitaxial strain
K. Madani, Q. N. Meier, A. Cano
Nickelate materials exhibit rich electronic properties that can be engineered toward cuprate-like regimes through topotactic and mixed-anion chemistry. Using first-principles calcu…
Pressure and doping effects on the electronic structure and magnetism of the single-layer nickelate LaNiO
J. B. de Vaulx, F. Bernardini, V. Olevano +2
LaNiO is a prototypical member of the Ruddlesden-Popper nickelate series that offers a valuable reference point for elucidating the key ingredients behind the intriguing pr…
Capping effects on spin and charge excitations in parent and superconducting Nd1-xSrxNiO2
S. Fan, H. LaBollita, Q. Gao +19
Superconductivity in infinite layer nickelates Nd1-xSrxNiO2 has so far been achieved only in thin films raising questions on the role of substrates and interfaces. Given the challe…
Magnetic and structural properties of the iron silicide superconductor LaFeSiH
M. F. Hansen, S. Layek, J. -B. Vaney +20
The magnetic and structural properties of the recently discovered pnictogen/chalcogen-free superconductor LaFeSiH (~K) have been investigated by Fe synchrotron…
Preempted phonon-mediated superconductivity in the infinite-layer nickelates
Q. N. Meier, J. B. de Vaulx, F. Bernardini +4
Nickelate superconductors are outstanding materials with intriguing analogies with the cuprates. These analogies suggest that their superconducting mechanism may be unconventional,…
