使用光开关皮秒脉冲光谱仪对钡铁氧体压制粉末样品进行了透射率测量。通过与同一样品的毫米波光谱进行比较，在脉冲光谱中发现了与亚铁磁共振相关的特征。从渗透率模型预测的时域谱表明与实验短脉冲线形状存在显着差异。
Transmission measurements of a barium ferrite pressed-powder sample have been made with an optically switched picosecond-pulse spectrometer. By comparison to millimeter-wave spectroscopy of the same sample, features related to the ferrimagnetic resonance have been identified in the pulse spectrum. Time-domain spectra predicted from models of the permeability indicate significant discrepancies with the experimental short-pulse line shape.
