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…
Measurement of the Spin Absorption Anisotropy in Lateral Spin Valves
Maxen Cosset-Chéneau, Laurent Vila, Gilles Zahnd +7
The spin absorption process in a ferromagnetic material depends on the spin orientation relativelyto the magnetization. Using a ferromagnet to absorb the pure spin current created…
A switchable two-dimensional electron gas based on ferroelectric Ca:SrTiO
Julien Bréhin, Felix Trier, Luis M. Vicente-Arche +14
Two-dimensional electron gases (2DEGs) can form at the surface of oxides and semiconductors or in carefully designed quantum wells and interfaces. Depending on the shape of the con…
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…
Negligible thermal contributions to the spin pumping signal in ferromagnetic metal-Platinum bilayers
Paul Noël, Maxen Cosset-Cheneau, Victor Haspot +6
Spin pumping by ferromagnetic resonance is one of the most common technique to determine spin hall angles, Edelstein lengths or spin diffusion lengths of a large variety of materia…
Cross-shaped nanostructures for the study of spin to charge interconversions using spin-orbit coupling in non-magnetic materials
V. T. Pham, L. Vila, G. Zahnd +3
Several spin-orbit effects allow performing spin to charge inter-conversion: the spin Hall effects, the Rashba effect, or the spin-momentum locking in topological insulators. Here…
Large enhancement of the spin Hall effect in Au by scattering with side-jump on Ta impurities
P. Laczkowski, Y. Fu, H. Yang +16
We present measurements of the Spin Hall Effect (SHE) in AuW and AuTa alloys for a large range of W or Ta concentrations by combining experiments on lateral spin valves and Ferroma…
Spin Pumping and Inverse Spin Hall Effect in Germanium
J. -C. Rojas-Sánchez, M. Cubukcu, A. Jain +13
We have measured the inverse spin Hall effect (ISHE) in \textit{n}-Ge at room temperature. The spin current in germanium was generated by spin pumping from a CoFeB/MgO magnetic tun…
Crossover from spin accumulation into interface states to spin injection in the germanium conduction band
A. Jain, J. -C. Rojas-Sanchez, M. Cubukcu +18
Electrical spin injection into semiconductors paves the way for exploring new phenomena in the area of spin physics and new generations of spintronic devices. However the exact rol…
