Thermally 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 ...

Current-induced skyrmion generation and dynamics in symmetric bilayers

Magnetic skyrmions are quasiparticle-like textures which are topologically different from other states. Their discovery in systems with broken inversion symmetry sparked the search for materials containing such magnetic phase at room temperature. Their topological properties combined with the chirality-related spin-orbit torques make them interesting objects to control the magnetization at nano...

Skyrmion 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...

Current and noise suppression in ac-driven coherent transport

We investigate the possibility to manipulate for the transport through heterostructures the dc current and its noise properties by an ac gate voltage. For a computation of the noise strength, we map the system to a tight-binding model for which noise suppression by ac fields has been predicted recently. The quality of this description is tested by comparing the transmission of the tight-binding...

ac current generation in chiral magnetic insulators and Skyrmion motion induced by the spin Seebeck effect.

We show that a temperature gradient induces an ac electric current in multiferroic insulators when the sample is embedded in a circuit. We also show that a thermal gradient can be used to move magnetic Skyrmions in insulating chiral magnets: the induced magnon flow from the hot to the cold region drives the Skyrmions in the opposite direction via a magnonic spin transfer torque. Both results ar...
