我们提出了一种混合使用的畴壁和skyrmions在同一赛道存储器，可以使开发一个平台，多值磁数据存储技术，通过数值求解Landau-Lifshitz-吉尔伯特方程。在没有几何限制的普通纳米轨道中将畴壁转换为磁性skyrmions使我们能够实现三元赛道存储器。反向畴的零化、转换和越过被认为是三值逻辑的三态。我们预计，多位赛道内存将影响新兴计算技术的数据存储平台的发展。
We present a hybrid usage of domain walls and skyrmions in the same racetrack memory which can enable developing a platform for many-valued magnetic data storage technology, by numerically solving the Landau–Lifshitz-Gilbert equation. The conversion of domain-walls to magnetic skyrmions in a plain nanotrack without geometrical restrictions allowed us to realize a ternary racetrack memory. Annihilation, conversion, and passing over of the reverse domains are considered as the three-state of ternary logic. We anticipate that multibit racetrack memory will influence the development of data storage platforms for emergent computing technologies.
