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,…
Thin-film aspects of superconducting nickelates
F. Bernardini, L. Iglesias, M. Bibes +1
The discovery of superconductivity in infinite-layer nickelates has attracted much attention due to their association to the high- cuprates. Cuprate superconductivity was firs…
Unconventional disorder effects in correlated superconductors
Maria N. Gastiasoro, Fabio Bernardini, Brian M. Andersen
The understanding of disorder has profoundly influenced the development of condensed matter physics, explaining such fundamental effects as, for example, the transition from ballis…
