磁skyrmions半径与密度的关系
The relation between the radii and the densities of magnetic skyrmions
摘要：
与传统的磁泡相比，Skyrmion具有更小的尺寸，更好的稳定性，因此被认为是一种非常有前途的存储器件。当操纵、擦除和创造Skyrmion时，Skyrmion的密度可以改变，但Skyrmion的半径和密度之间的关系需要更多的探索。在本文中，我们研究了这个问题的理论和使用晶格模拟。得到并验证了Skyrmions平均半径随材料参数、外磁场强度和Skyrmions密度的变化关系。利用此显式函数，可以方便地预测Skyrmion的半径，这对Skyrmion存储器件的进一步研究是有帮助的。
英文摘要：
Compared with the traditional magnetic bubble, skyrmion has smaller size, better stability therefore is considered as a very promising candidate for future memory devices. When skyrmions are manipulated, erased and created, the density of skyrmions can be varied, however the relationship between the radii and the densities of skyrmions needs more exploration. In this paper, we study this problem both theoretically and by using the lattice simulation. The average radius of skyrmions as a function of material parameters, the strength of external magnetic field and the density of skyrmions is obtained and verified. With this explicit function, the skyrmion radius can be easily predicted, which is helpful for the future study of skyrmion memory devices.
