摘要：
The Verdet constant of poly-alpha-methylstyrene fiber doped with a biphenyl compound showed a value beyond 0.09 min.Oe-1.cm-1 at 488 nm. The optical fiber isolator for the 488-nm laser, which was constructed using the above plastic fiber and a pulse magnetic field, had about 20-dB isolation. This plastic fiber could also be used as an optical sensor head for monitoring higher current in a planar discharge circuit.
