Spin–orbit coupling induced magnetoresistance oscillation in a dc biased two-dimensional electron system
Abstract:
We study dc-current effects on the magnetoresistance oscillation in a two-dimensional electron gas with Rashba spin-orbit coupling, using the balance-equation approach to nonlinear magnetotransport. In the weak current limit the magnetoresistance exhibits periodical Shubnikov-de Haas oscillation with changing Rashba coupling strength for a fixed magnetic field. At finite dc bias, the period of the oscillation halves when the interbranch contribution to resistivity dominates. With further increasing current density, the oscillatory resistivity exhibits phase inversion, i.e., magnetoresistivity minima (maxima) invert to maxima (minima) at certain values of the dc bias, which is due to the current-induced magnetoresistance oscillation.

Magnetic Field due to Moving Charges
Consider a point charge moving with a constant velocity.

However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...
