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…

Strain-driven magnetic anisotropy and spin reorientation in epitaxial Co V 2 O 4 spinel oxide thin films

Lamiae El Khabchi, Laurent Schlur, Jérôme Robert +9

CoV___O___ (CVO) stands out among spinel vanadates for its ultra-short V-V distances, placing it at the brink of itinerant electron behaviour-an ideal playground for strain enginee…

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…
