Magnetotransport in 2D electron systems with a Rashba spin-orbit interaction

TL;DR

This paper models and explains the beating pattern of Shubnikov-de Haas oscillations in 2D electron systems with Rashba spin-orbit interaction, confirming the magnetic field independence of the interaction strength.

Contribution

It provides explicit formulae for node positions in oscillations considering Zeeman splitting, aligning theory with experimental data.

Findings

The beating pattern is well reproduced by the model.

The Rashba spin-orbit interaction strength is field-independent.

The explicit formulae accurately describe experimental observations.

Abstract

The beating pattern of Shubnikov-de Haas oscillations in 2D electron system in the presence of a Rashba zero-field spin splitting is reproduced. It is shown, taking into account the Zeeman splitting, that the explicit formulae for the node position well describes the experimental data. The spin-orbit interaction strength obtained is found to be magnetic field independent in an agreement with the basic assumptions of the Rashba model.
