摘要：

Transient magneto-optic effects in ferrofluid-filled microstructured optical fibers are considered. Magneto-optic responses of two types, i.e., an even and an odd one, were observed in the longitudinal geometry of an applied pulsed magnetic field for the kerosene-based Fe3O4 ferrofluid with similar to 8 nm nanoparticles. For the first time a submicrosecond response time limited by the rise time of the applied field pulse (similar to 0.35 mu s) was demonstrated for the odd magneto-optic effect in an all-fiber system, and responses of the even and odd magneto-optic effects were separated. A strong influence of the pulse width on the relaxation time of the even response is attributed to the formation of particle aggregates. Copyright (C) EPLA, 2015
