论文摘要
我们已经研究了强烈的偶极耦合,高度各向异性纳米群岛的自旋波模式,形成了平方人造自旋冰系统,使用Mumax3中的微磁模拟与MATLAB编码结合使用。人造自旋冰被认为是由椭圆横截面纳米群的四个方形环型结构形成的。我们的结果表明,生成的自旋波模式与系统中形成的微型状态之间的直接关系。我们已经表明,单个环类型结构仅被充分地用于理解正方形人造自旋冰的自旋波模式。
We have investigated the spin wave modes of strongly dipolar coupled, highly anisotropic nanoislands forming square artificial spin ice system using micromagnetic simulation in MUMAX3 in combination with Matlab coding. Artificial spin ice is considered to be formed by the four square ring-type structure of elliptical cross-section nanoislands. Our results state the direct relation between the spin wave modes generated and the micro-states formed in the system. We have shown that single ring type structure can alone be adequately used to understand the spin wave modes of square artificial spin ice.
