Spin and orbital excitations in undoped infinite layers: a comparison between superconducting PrNiO2 and insulating CaCuO2
Francesco Rosa, Hoshang Sahib, Giacomo Merzoni +9
Infinite-layer nickelates are among the most promising cuprate-akin superconductors, although relevant differences from copper oxides have been reported. Here, we present momentum-…
Decoding Superconductivity in LaNiO Thin Films via Ozone-Driven Structure and Oxidation Tuning
Mathieu Flavenot, Hoshang Sahib, Jérôme Robert +6
The discovery of superconductivity in bulk Ruddlesden-Popper LaNiO(LNO327) under high hydrostatic pressure has redefined the recent experimental consensus that nickelat…
Tailoring the breathing-mode distortions in nickelate-ferroelectric heterostructures
Guillaume Krieger, Chia-Ping Su, Hoshang Sahib +5
In transition metal oxides electron-electron interaction and lattice degree of freedom are basic ingredients of emergent phenomena, such as metal-to-insulator transition (MIT) and…
Superconductivity in PrNiO2 infinite-layer nickelates
Hoshang Sahib, Francesco Rosa, Aravind Raji +6
Several reports about infinite-layer nickelate thin films suggest that the superconducting critical temperature versus chemical doping phase diagram has a dome-like shape, similar…
Signatures of canted antiferromagnetism in infinite-layer nickelates studied by x-ray magnetic dichroism
G. Krieger, H. Sahib, F. Rosa +10
We report an experimental study of the magnetic properties of infinite-layer Nd1-xSrxNiO2 thin films by x-ray magnetic circular dichroism (XMCD) at Ni L3,2 and Nd M5,4 edges. We sh…
