All-Optical Magnetothermoelastic Skyrmion Motion
نویسندگان
چکیده
The author's calculations show that magnetic skyrmions in metallic multilayers such as Co/Pt can be controllably moved on surfaces, simply by using a focused laser beam. Temperature gradients at the spot directly yield skyrmion motion, due to temperature dependence of parameters, but another contribution even more important: Thermoelastic lattice expansion results strain-induced local gradient anisotropy. This method displacement allows full control motion over surface, with possible path MEMS-VCSEL on-chip integration.

Magnetic skyrmion transistor: skyrmion motion in a voltage-gated nanotrack
Magnetic skyrmions are localized and topologically protected spin configurations, which are of both fundamental and applied interests for future electronics. In this work, we propose a voltage-gated skyrmion transistor within the well-established framework of micromagnetics. Its operating conditions and processes have been theoretically investigated and demonstrated, in which the gate voltage c...
متن کاملDeveloping All-Skyrmion Spiking Neural Network
In this work, we have proposed a revolutionary neuromorphic computing methodology to implement All-Skyrmion Spiking Neural Network (AS-SNN). Such proposed methodology is based on our finding that skyrmion is a topological stable spin texture and its spatiotemporal motion along themagnetic nano-track intuitively interprets the pulse signal transmission between two interconnected neurons. In such...
متن کاملSkyrmion motion driven by oscillating magnetic field
The one-dimensional magnetic skyrmion motion induced by an electric current has attracted much interest because of its application potential in next-generation magnetic memory devices. Recently, the unidirectional motion of large (20 μm in diameter) magnetic bubbles with two-dimensional skyrmion topology, driven by an oscillating magnetic field, has also been demonstrated. For application in hi...
متن کاملThermally assisted current-driven skyrmion motion
We study the behavior of skyrmions in thin films under the action of stochastic torques arising from thermal fluctuations. We find that the Brownian motion of skyrmions is described by a stochastic Thiele’s equation and its corresponding Fokker-Planck equation. The resulting Fokker-Planck equation is recognized as the one for a high-friction Brownian particle which has been studied extensively ...
متن کاملSkyrmion-skyrmion Scattering
We study the scattering of Skyrmions at low energy and large separation using the method proposed by Manton of truncation to a finite number of degree freedom. We calculate the induced metric on the manifold of the union of gradient flow curves, which for large separation, to first non-trivial order is parametrised by the variables of the product ansatz.
