Charge-to-spin conversion in epitaxial and polycrystalline Bi and Bi/Ag layers
Federica Nasr, Emir Karadža, Santos F. Alvarado +9
Bi is predicted to be an efficient generator of spin-orbit torques (SOTs), with charge-to-spin conversion efficiency comparable to those of prototypical heavy metals, such as Ta, W…
Optically induced orbital polarization in bulk germanium
Francesco Scali, Marco Finazzi, Federico Bottegoni +1
Optical orientation has been proven as a powerful tool to inject spin-polarized electron and hole populations in III-V and group-IV semiconductors. In particular, the absorption of…
Electric Field Modulation of Spin Transport
Carlo Zucchetti, Adele Marchionni, Monica Bollani +3
The finite spin lifetime in solids is often considered a major hindrance for the development of spintronic devices, which typically require cryogenic temperatures to mitigate this…
Large Rashba unidirectional magnetoresistance in the Fe/Ge(111) interface states
T. Guillet, C. Zucchetti, A. Marty +8
The structure inversion asymmetry at surfaces and interfaces give rise to the Rashba spin-orbit interaction (SOI), that breaks the spin degeneracy of surface or interface states. H…
Spin-orbitronics at a topological insulator-semiconductor interface
T. Guillet, C. Zucchetti, A. Marchionni +9
Topological insulators (TIs) hold great promises for new spin-related phenomena and applications thanks to the spin texture of their surface states. However, a versatile platform a…
Observation of Large Unidirectional Rashba Magnetoresistance in Ge(111)
T. Guillet, C. Zucchetti, Q. Barbedienne +8
Relating magnetotransport properties to specific spin textures at surfaces or interfaces is an intense field of research nowadays. Here, we investigate the variation of the electri…
Tuning spin-charge interconversion with quantum confinement in ultrathin Bi/Ge(111) films
C. Zucchetti, M. -T Dau, F. Bottegoni +16
Spin-charge interconversion (SCI) phenomena have attracted a growing interest in the field of spintronics as means to detect spin currents or manipulate the magnetization of ferrom…
Enhancement of Spin Currents in a Lattice near the Curie Point
Marco Finazzi, Federico Bottegoni, Carlo Zucchetti +2
We show that pure spin currents carried by conduction electrons injected into a paramagnetic lattice of mutually interacting localized magnetic moments can be enhanced close to the…
Non-local opto-electrical spin injection and detection in germanium at room temperature
Fabien Rortais, Carlo Zucchetti, Lavinia Ghirardini +13
Non-local carrier injection/detection schemes lie at the very foundation of information manipulation in integrated systems. This paradigm consists in controlling with an external s…
