建立了一套脉冲磁场下的显微法拉第旋转测量系统，该系统可用于微米级抗磁性和顺磁性材料的测量。脉冲磁线圈可以产生约12 T的最大磁通密度。在使用玻璃板作为标准材料校准脉冲磁通密度之后，通过测量聚苯乙烯颗粒的费尔德常数V来证明显微法拉第旋转装置的性能。同时，还测量了一些抗磁性物质的磁光色散，并用V= a λ（-2）+B进行了分析。将a和B的值与它们的磁化率进行比较。
Microscopic Faraday rotation measurement system using a pulsed magnetic field has been constructed, which can be applied to micron sized diamagnetic and paramagnetic materials. A pulsed magnetic coil could generate a maximum magnetic flux density of about 12 T. The performance of the microscopic Faraday rotation apparatus was demonstrated by the measurement of the Verdet constant V of a polystyrene particle, after the calibration of the pulsed magnetic flux density using a glass plate as a standard material. Also, the magneto-optical rotation dispersion of some diamagnetic substances have been measured and analyzed with V=alambda(-2)+b. The values of a and b were compared to their magnetic susceptibilities.
