回顾了最近的时间分辨扫描克尔显微镜实验和微磁学模拟的磁化动力学在单个纳米磁体,并在偶极耦合纳米磁体对。两个纳米磁体系统。在单个440 nm正方形中,探索了脉冲场振幅对中心型和边缘型限制自旋波模式相对振幅的影响。此外,在不同的磁基态观察到的动力学阻尼的差异进行了讨论。在成对的300 nm的磁盘,结构缺陷和静态偶极场的边缘模式分裂的相对效果进行了研究作为磁盘分离的函数。
A review is provided of recent time-resolved scanning Kerr microscopy experiments and micromagnetic simulations of magnetization dynamics in single nanomagnets, and in pairs of dipolar coupled nanomagnets. Two nanomagnet systems are presented. In a single 440 nm square, the effect of the pulsed field amplitude on the relative amplitudes of center- and edge-type confined spin wave modes is explored. In addition, the difference in the damping of dynamics observed in different magnetic ground states is discussed. In pairs of 300 nm disks, the relative effect of structural imperfections and static dipolar fields on the splitting of edge-modes is investigated as a function of disk separation.
