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…
Spin excitations in Nd1-xSrxNiO2 and YBa2Cu3O7-delta: the influence of Hubbard U
Francesco Rosa, Leonardo Martinelli, Guillaume Krieger +10
We use Resonant Inelastic X-ray Scattering (RIXS) to compare the doping dependence of magnetic excitations of an Infinite-Layer nickelate to those of a prototypical superconducting…
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…
Scanning tunnelling microscopy and X-ray photoemission studies of NdNiO2 infinite-layer nickelates films
Martando Rath, Yu Chen, Guillaume Krieger +3
We report scanning tunnelling microscopy (STM) and x-ray photoemission spectroscopy (XPS) measurements on uncapped and SrTiO3 (STO) capped NdNiO2 realized by pulsed-laser depositio…
Charge distribution across capped and uncapped infinite-layer neodymium nickelate thin films
Aravind Raji, Guillaume Krieger, Nathalie Viart +3
Charge ordering (CO) phenomena have been widely debated in strongly-correlated electron systems mainly regarding their role in high-temperature superconductivity. Here, we elucidat…
Synthesis of infinite-layer nickelates and influence of the capping-layer on magnetotransport
Guillaume Krieger, Aravind Raji, Laurent Schlur +7
The recent discovery of a zero-resistance state in nickel-based compounds has generated a re-excitement about the long-standing problem in condensed matter of high-critical-tempera…
