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 ...

Electrically Controlled Pumping of Spin Currents in Topological Insulators [PDF]
Physical Review B, 2011 Pure spin currents are shown to be generated by an electrically controlled quantum pump applied at the edges of a topological insulator. The electric rather than the more conventional magnetic control offers several advantages and avoids, in particular ...

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.

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 ...

Controlling the Interlayer Dzyaloshinskii–Moriya Interaction by Electrical Currents
Nano Letters, 2023 The recently discovered interlayer Dzyaloshinskii-Moriya interaction (IL-DMI) in multilayers with perpendicular magnetic anisotropy favors canting of spins in the in-plane direction. It could thus stabilize intriguing spin textures such as Hopfions. A key requirement for nucleation is to control the IL-DMI. Therefore, we investigate the influence of an

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