Coherence and dissipation of spin-wave eigen modes in magnetic micro- and nano-structures

主题是光刻制备的亚微米磁岛的时空动力学。利用布里渊光散射技术研究了自旋波本征模谱与畴结构的关系。在“傅立叶显微镜”模式下利用布里渊光散射，可以确定自旋波模式强度的空间分布，并提供了在单个域内研究自旋波局部化效应的途径。第二个主题是磁岛之间的动态耦合为小岛屿分离。

Subject is the spatio-temporal dynamics in lithographically prepared sub-micrometer magnetic islands with domains. Using the Brillouin light scattering technique the spin wave eigenmode spectrum is investigated as a function of the domain structure. The utilization of Brillouin light scattering in the "Fourier microscope" mode allows the determination of the spatial distribution of the spin wave mode intensities and it provides access to spin wave localization effects in individual domains. A second subject is the dynamic coupling between magnetic islands for small island separations.
