Orbital and Spin Edelstein Effects in KTaO(110) Two-Dimensional Electron Gases
Hugo Witt, Aravind Raji, Srijani Mallik +16
The orbital Edelstein effect converts an electric field into a non-equilibrium orbital polarization, opening new opportunities for orbitronics. Although signatures of the orbital E…
Electronic bandstructure of superconducting KTaO3 (111) interfaces
Srijani Mallik, Börge Göbel, Hugo Witt +17
Two-dimensional electron gases(2DEGs)based on KTaO3 are emerging as a promising platform for spin-orbitronics due to their high Rashba spin-orbit coupling (SOC) and gate-voltage tu…
Gate-voltage switching of non-reciprocal transport in oxide-based Rashba interfaces
Julien Bréhin, Luis M. Vicente Arche, Sara Varotto +6
The linear magnetoelectric effect (ME) is the phenomenon by which an electric field produces a magnetization. Its observation requires both time-reversal and space-inversion symmet…
All-electrical detection of the spin-charge conversion in nanodevices based on SrTiO3 two-dimensional electron gases
Fernando Gallego, Felix Trier, Srijani Mallik +12
The Magnetoelectric Spin-Orbit (MESO) technology aims to bring logic into memory by combining a ferromagnet with a magnetoelectric (ME) element for information writing, and a spin-…
Visualizing giant ferroelectric gating effects in large-scale WSe/BiFeO heterostructures
Raphaël Salazar, Sara Varotto, Céline Vergnaud +13
Multilayers based on quantum materials (complex oxides, topological insulators, transition-metal dichalcogenides, etc) have enabled the design of devices that could revolutionize m…
Direct visualization of Rashba-split bands and spin/orbital-charge interconversion at KTaO interfaces
Sara Varotto, Annika Johansson, Börge Göbel +10
Rashba interfaces have emerged as promising platforms for spin-charge interconversion through the direct and inverse Edelstein effects. Notably, oxide-based two-dimensional electro…
A multiferroic two-dimensional electron gas
Julien Bréhin, Yu Chen, Maria D'Antuono +6
Multiferroics are compounds in which at least two ferroic orders coexist - typically (anti)ferromagnetism and ferroelectricity. While magnetic order can arise in both insulating an…
Spin-charge interconversion in KTaO two-dimensional electron gases
Luis M. Vicente-Arche, Julien Bréhin, Sara Varotto +22
Oxide interfaces exhibit a broad range of physical effects stemming from broken inversion symmetry. In particular, they can display non-reciprocal phenomena when time reversal symm…
Room-temperature ferroelectric switching of spin-to-charge conversion in GeTe
Sara Varotto, Luca Nessi, Stefano Cecchi +17
Since its birth in the 1990s, semiconductor spintronics has suffered from poor compatibility with ferromagnets as sources of spin. While the broken inversion symmetry of some semic…
Independence of the inverse spin Hall effect with the magnetic phase in thin NiCu films
Sara Varotto, Maxen Cosset-Cheneau, Cécile Grezes +10
Large spin Hall angles have been observed in 3d ferromagnets, but their origin, and especially their link with the ferromagnetic order, remain unclear. Here, we investigate the inv…
Fe/GeTe(111) heterostructures as an avenue towards 'ferroelectric Rashba semiconductors'-based spintronics
Jagoda Slawinska, Domenico Di Sante, Sara Varotto +3
By performing density functional theory (DFT) and Green's functions calculations, complemented by X-ray Photoemission Spectroscopy, we investigate the electronic structure of Fe/Ge…
Ferroelectric control of the spin texture in germanium telluride
C. Rinaldi, S. Varotto, M. Asa +9
The electrical manipulation of spins in semiconductors, without magnetic fields or auxiliary ferromagnetic materials, represents the holy grail for spintronics. The use of Rashba e…
