论文摘要
在纳米版本中,对天空操纵的需求不断增加,这使有趣的研究提出了8个了解这些受拓扑保护的手性结构的稳定。为了了解实验观察到的实际形状9和Skyrmion的大小,我们进行了微磁模拟,研究了在磁性薄膜系统中随机各向异性存在下的10个天际稳定。以前的实验11次薄膜中天空成像的报道描绘了天际形状不是完全圆形的。在这里,我们12通过模拟显示,由于存在不同的局部13各向异性能量,Skyrmion的形状可能会变形。单轴各向异性常数(KU)和随机型态度常数(KR)14的值有所不同,以了解在15平方磁性纳米元素中稳定的Skymion的形状和大小的变化。 Skyrmion的形状被扭曲,并且系统中的高随机16各向异性能量的尺寸变得恒定。
Ever increasing demand of skyrmion manipulation in nanodevices has brought up interesting research to 8 understand the stabilization of these topologically protected chiral structures. To understand the actual shape 9 and size of skyrmion observed experimentally, we have performed micromagnetic simulations to investigate 10 skyrmion stabilization in presence of random anisotropy in magnetic thin film system. Previous experimental 11 reports of skyrmion imaging in thin films depicts that the skyrmion shape is not perfectly circular. Here we 12 show via simulations that the shape of a skyrmion can get distorted due to the presence of different local 13 anisotropy energy. The values of uniaxial anisotropy constant (Ku) and random aniostropy constant (Kr) 14 are varied to understand the change in shape and size of a skyrmion and an antiskyrmion stabilized in a 15 square magnetic nanoelement. The skyrmion shape gets distorted and the size gets constant for high random 16 anisotropy energy in the system.
