Spin and Orbital Rashba response in ferroelectric polarized PtSe/MoSe/LiNbO heterostructures

Armando Pezo, Sylvain Massabeau, Filip Miljević +6

Recent studies using Terahertz Time-Domain Spectroscopy (THz-TDS) with spintronic emitters as a source have revealed distinct signatures of the Rashba effect. This effect, which ar…

Room temperature magnetic vortices in the van der Waals magnet FeGeTe

Elias Sfeir, Carolin Schrader, Florentin Fabre +8

We investigate the effect of confinement on the magnetic state of a 12 nm-thick FeGeTe layer grown by molecular beam epitaxy. We use quantitative scanning NV magnetometry t…

Giant spin-to-charge conversion in germanium tin epilayers

S. Oyarzún, C. Gonzalez-Fuentes, Erick Burgos +4

We report a study of the spin-to-charge current conversion in compressively strained Ge1-xSnx alloy epilayers as a function of the Sn concentration by means of the inverse spin Hal…

Monolayer control of spin-charge conversion in van der Waals heterostructures

K. Abdukayumov, O. Paull, M. Mičica +25

The diversity of 2D materials and their van der Waals (vdW) stacking presents a fertile ground for engineering novel multifunctional materials and quantum states of matter. This pe…

Inverse Rashba-Edelstein THz emission modulation induced by ferroelectricity in CoFeB/PtSe2/MoSe2//LiNbO3 systems

S. Massabeau, O. Paull, A. Pezo +10

Spintronic Terahertz emitters, based on optically triggered spin-to-charge interconversion processes, have recently emerged as novel route towards compact and efficient THz sources…
