| Abstract: | 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. |
