dc.description.abstract |
Magnetic skyrmion, which is one of the topologically stable magnetic configurations, has been regarded as a good candidate to develop future spintronic devices due to its rich dynamic properties and tiny size [1]. It can be created by using a material defect, or the geometrical constriction [3, 4]. However, most of the study on the creation of magnetic skyrmion has been considered the magnetic skyrmion in a film or a nanowire, not a patterned disk although the magnetic skyrmion in a patterned disk has lots of unique dynamic excitations such as gyrotropic and breathing modes [3]. Here, we propose novel method to generate skyrmions in a patterned disk with desire direction from micromagnetic studies. We modeled conventional multilayer structure of [Pt (3 nm)/Co4Fe4B2 (0.8 nm)/MgO (1.5 nm)]20 with material parameters in Ref. [5]. To explore the generation of the skyrmions in a patterned disk, various time-varying currents were applied along in-plane direction. We found that the rotating current generate the magnetic skyrmions from the labyrinth domain, and the rotational direction of the electrical current determines a polarization of magnetic skyrmion. The detailed manipulation process of magnetic skyrmion will be discussed at the presentation. |
