摘要
在铁磁共振实验中，通过铁磁共振曲线测量共振线宽十分重要，因为它表示铁磁材料磁损耗的大小。频散效应对铁磁共振曲线有明显的影响，该文从理论上分析了频散效应的物理本质以及它对铁磁共振曲线的影响，阐述了测量共振线宽的具体实验方法。
It is very important to measure ferroruagnetic resonance linewidth AB by ferromagnetic resonance curves because AB displays the ferromagnetic loss of magnetic materials. Frequency dispersion has an obvious influence on the ferromagnetic resonance curve. The physical nature of frequency dispersion and the effect of frequency dispersion on the ferromagnetic resonance curve have been analyzed from theory. Experimential method to measure the ferromagnetic resonant linewidth is also illustrated.
