Abstract
- Magnetic skyrmion, a nano-sized spin texture with topological property, have the potential to develop high-density, low-power, and multifunctional spintronic devices. To realize the reconfiguration of a single logic device and the implementation of the complete logic functions, a new reconfigurable and reusable skyrmion logic is proposed and verified by micromagnetic simulation. Logic functions including AND, OR, NOT, NAND and NOR are realized in ferromagnetic (FM) nanotrack by skyrmion-edge repulsions and the voltage control of magnetic anisotropy (VCMA) effect. The working state of the potential well can be controlled by the link of the input signals, thus changing the function type. In addition, through reusing skyrmion in circular track, the energy required for creation and deletion is reduced. This work can provide guidance for the design and optimization of reconfigurable and reusable logic devices with circular track based on skyrmion.
