Electric Control of Spin Currents and Spin-Wave Logic [PDF]

open access: yesPhysical Review Letters, 2011
Spin waves in insulating magnets are ideal carriers for spin currents with low energy dissipation. An electric field can modify the dispersion of spin waves, by directly affecting, via spin-orbit coupling, the electrons that mediate the interaction between magnetic ions.

Stability analysis and nonlinear current-limiting control design for DC micro-grids with CPLs

open access: yesIET Smart Grid, 2020
In this study, a DC micro-grid consisting of multiple paralleled energy resources interfaced by both bidirectional AC/DC and DC/DC boost converters and loaded by a constant power load (CPL) is investigated. By considering the generic dq transformation of

An electrically controlled quantum dot based spin current injector [PDF]

open access: yesNanoscale, 2012
We present a proposal for a fully electrically controllable quantum dot based spin current injector. The device consists of a quantum dot that is strongly coupled to a ferromagnetic electrode on one side and weakly coupled to a nonmagnetic electrode on the other side.

Non-linear MPC for winding loss optimised torque control of anisotropic PMSM

open access: yesThe Journal of Engineering, 2019
For a non-linear anisotropic permanent magnet synchronous machine (PMSM), a prediction model for model predictive control (MPC) considering effects like cross-coupling and saturation is developed in a straight forward procedure.
