Contribution
It introduces a simulation-based analysis of Skyrmion manipulation techniques using STM, highlighting new methods for controlling magnetic Skyrmions at the atomic scale.
Findings
Skyrmion creation and annihilation can be controlled with STM.
Single Skyrmion movement is demonstrated in simulations.
Electric fields and spin-polarized currents are effective manipulation tools.
Abstract
The dynamics of a single magnetic Skyrmion in an atomic spin system under the influence of Scanning Tunneling Microscope is investigated by computer simulations solving the Landau-Lifshitz-Gilbert equation. Two possible scenarios are described: manipulation with aid of a spin-polarized tunneling current and by an electric field created by the scanning tunneling microscope. The dynamics during the creation and annihilation process is studied and the possibility to move single Skyrmions is showed.
