This works deals with the presence of localized planar structures in magnetic materials that admit integer or half-integer topological charge. We study models in which the internal disposition of magnetization is driven by a single parameter, that controls the topological charge density of the magnetic structure. In particular, we focus mainly on the configurational entropy of these skyrmions and half-skyrmions and show how to increase or diminish their informational capabilities.

平面磁性元件中天空和半天空的构型熵

这项工作解决了磁性材料中存在局部平面结构的问题,这种结构允许整数或半整数拓扑电荷。我们研究的模型中,内部磁化强度由单个参数驱动,该参数控制磁性结构的拓扑电荷密度。特别是,我们主要关注这些天空形和半天空形的构型熵,并说明如何增加或减小它们的信息能力。
