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…
