提出了一种研究单个磁性纳米元件吉赫磁化动力学的方法。通过将频域方法与微焦点克尔效应检测相结合，实现了对磁化动力学的高灵敏度和亚微米空间分辨率。它允许记录单个纳米结构的光谱。给出了软磁薄片中均匀进动的结果。
We present a method for the investigation of gigahertz magnetization dynamics of single magnetic nano elements. By combining a frequency domain approach with a micro focus Kerr effect detection, a high sensitivity to magnetization dynamics with submicron spatial resolution is achieved. It allows spectra of single nanostructures to be recorded. Results on the uniform precession in soft magnetic platelets are presented.
