The structure inversion asymmetry at surfaces and interfaces gives rise to the Rashba spin-orbit interaction (SOI), that breaks the spin degeneracy of surface or interface states. Hence, when an electric current runs through a surface or interface, this Rashba effect generates an effective magnetic field acting on the electron spin. This provides an additional tool to manipulate the spin state in materials such as Si and Ge possessing inversion symmetry in their bulk form. The existence of…

Anomalous Hall unidirectional magnetoresistance
We predict an anomalous-Hall unidirectional magnetoresistance (AH-UMR) in conducting bilayers composed of a ferromagnetic layer and a nonmagnetic layer, which does not rely on the spin Hall effect in
Theory of unidirectional magnetoresistance and nonlinear Hall effect
Two different formalisms are compared to derive the nonlinear conductivities of the unidirectional magnetoresistance and the non linear Hall effect in the ferromagnetic Rashba model and both converge to the same analytical formula in the limit of infinite relaxation time.


Determining the Rashba parameter from the bilinear magnetoresistance response in a two-dimensional electron gas
Two-dimensional (2D) Rashba systems have been intensively studied in the last decade due to their unconventional physics, tunability capabilities, and potential for spin-charge interconversion when
Observation of Large Unidirectional Rashba Magnetoresistance in Ge(111).
This work investigates the variation of the electrical resistance of Ge(111) grown epitaxially on semi-insulating Si(111), and ascribes the origin of this magnetoresistance to the interplay between the externally applied magnetic field and the pseudomagnetic field generated by the current applied in the spin-splitted subsurface states.

A giant spin-to-charge conversion in metallic states at the Fe/Ge(111) interface due to the Rashba coupling is shown and very large charge currents are generated by direct spin pumping into the interface states from 20 K to room temperature.
