孤子的自旋动力学研究
A spin dynamics approach to solitonics
摘要：
正是空间色散导致了交换相互作用和磁有序的出现。相反，存在于任何实际材料中的磁晶各向异性给运动方程带来一定的非线性。不同于均匀铁磁有序的各种非共线的基态配置之间的交换，各向异性和偶极-偶极相互作用的竞争的结果出现。这些粒子状的状态，例如磁孤子，skyrmion，畴壁，形成了一个空间局域的磁能凝块。在本文中，我们探讨拓扑保护磁孤子，可能会被应用于逻辑运算和/或信息存储在快速发展的领域的孤子（和skyrmionics）。能够轻松地创建，地址，和操纵这样的结构的先决条件之一，形成一个基础的-onics技术，并在这里详细研究使用数值和分析工具。
英文摘要：
It is spatial dispersion which is exclusively responsible for the emergence of exchange interaction and magnetic ordering. In contrast, magneto-crystalline anisotropy present in any realistic material brings in a certain non-linearity to the equation of motion. Unlike homogeneous ferromagnetic ordering a variety of non-collinear ground state configurations emerge as a result of competition among exchange, anisotropy, and dipole-dipole interaction. These particle-like states, e.g. magnetic soliton, skyrmion, domain wall, form a spatially localised clot of magnetic energy. In this paper we explore topologically protected magnetic solitons that might potentially be applied for logical operations and/or information storage in the rapidly advancing filed of solitonics (and skyrmionics). An ability to easily create, address, and manipulate such structures is among the prerequisite forming a basis of -onics technology, and is investigated in detail here using numerical and analytical tools.
