Non-volatile Orbital magnetoelectric effect in a two-dimensional electron gas
Yu Chen, Martando Rath, Julien Brehin +10
Electrical control of orbital magnetism is a central goal of orbitronics. While current-induced orbital polarization has recently been demonstrated in inversion-asymmetric systems,…
Electric-Field Control of Quantum Tunneling Regimes in Focused He-Ion-Beam-Irradiated Oxide Interfaces
Yu Chen, Maria D'Antuono, Robin Hutt +6
Helium focused ion beam irradiation enables the fabrication of tunnel field-effect transistors based on two-dimensional electron systems (2DESs) at an oxide interface.High resoluti…
Spin Hall and Edelstein effects in a ballistic quantum dot with Rashba spin-orbit coupling
Alfonso Maiellaro, Francesco Romeo, Mattia Trama +11
We study spin-resolved transport in a ballistic quantum dot with Rashba spin-orbit coupling, focusing on charge-to-spin conversion and spin Hall effect. In the regime where the dot…
Intrinsic Negative-U Centers in Freestanding LaAlO3/SrTiO3 Micro-membranes
Giulia Meucci, Pinelopi O. Konstantinopoulou, Thies Jansen +15
The LaAlO3/SrTiO3 (LAO/STO) interface hosts a rich range of electronic phenomena, including unconventional electron pairing that in quantum dots gives rise to a negative effective…
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-…
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…
Dirac-like fermions anomalous magneto-transport in a spin-polarized oxide two-dimensional electron system
Yu Chen, Maria D'Antuono, Mattia Trama +8
In two-dimensional electron systems (2DES) the breaking of the inversion, time-reversal and bulk crystal-field symmetries is interlaced with the effects of spin-orbit coupling (SOC…
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…
Electronic reconstruction at the interface between band insulating oxides: the LaAlO3/SrTiO3 system
M. Salluzzo
The conducting quasi-two dimensional electron system (q2DES) formed at the interface between LaAlO3 and SrTiO3 band insulators is confronting the condensed matter physics community…
