Electric current control of spin helicity in an itinerant helimagnet [PDF]
Nature Communications, 2020 The spin helicity in helimagnets may be exploited in magnetic memory applications if electrically controllable and detectable. Here, helicity manipulation driven by an electric current and detection by second harmonic resistivity measurements in an ...

Fast Finite-State Predictive Current Control of Electric Drives
IEEE Access, 2023 This work presents a novel optimization method for the implementation of finite-state model-based predictive current controllers in electrical drives. The proposal avoids the usual exhaustive search to find the control action, reducing the computational ...

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

Electrically controlled spin polarized current in Dirac semimetals [PDF]
Scientific Reports, 2021 Abstract We propose a highly tunable 100% spin-polarized current generated in a spintronics device based on Dirac semimetal under a magnetic field, which can be achieved merely by controlling electric parameters, i.e. the gate voltage, the barrier in the lead and the coupling strength between the leads and Dirac semimetal.

A controlled current inverter for an electric vehicle.
, 1993 The University of 'Canterbury Mark II' electric vehicle has been out of service for several years due to the lack of a suitable inverter to provide a variable frequency AC supply to its traction motors. This thesis describes the design and construction of such an inverter, using high current bipolar junction transistors as the switching elements, so ...

Controlling stable Bloch points with electric currents
Scientific Reports, 2023 AbstractThe Bloch point is a point singularity in the magnetisation configuration, where the magnetisation vanishes. It can exist as an equilibrium configuration and plays an important role in many magnetisation reversal processes. In the present work, we focus on manipulating Bloch points in a system that can host stable Bloch points—a two-layer FeGe ...
