综述了铁磁纳米结构中自旋波动力学的实验研究现状。分别描述了用于确定纳米级铁磁体共振响应的频率和场扫描光谱学的最新发展以及GHz频率和皮科秒时域中的时间分辨测量。微波激发到基态后的磁化弛豫的不同机制的分析和操纵的例子。
The current status of experimental approaches to analyze the spin wave dynamics in ferromagnetic nanoscale structures is reviewed. Recent developments in frequency- and field swept spectroscopy to determine the resonant response of nanoscale ferromagnets are described together with time-resolved measurements in the GHz frequency and pico second time domain, respectively. Examples for the analysis and manipulation of different mechanisms for the relaxation of the magnetization after microwave excitation into its ground state are presented.
