Frequency dependant susceptibility of dried grab samples from the navigation ...

To estimate the contribution of submicron-size superparamagnetic particles to the susceptibility signal, frequency-dependant susceptibility at 976 and 15.616 Hz was determined...为评估亚微米级超顺磁颗粒（submicron-size superparamagnetic particles）对磁化率信号（susceptibility signal）的贡献，本研究测定了976赫兹与15.616赫兹下的频率依赖性磁化率（frequency-dependant susceptibility）。
