在1.3μm波长垂直于光轴切割的1.2 mm厚的正方铁氧体晶体样品中，发现了几个μS持续时间的磁后效。后效应与去掉外部磁场后发生在单磁化样品中的相反磁化的磁化磁化成核和扩展有关。磁化反转过程在法拉第装置中可视化，并通过测量传输光束偏振态的时间依赖性来研究。
A magnetic aftereffect of several μs duration has been discovered in 1.2 mm thick samples of yttrium orthoferrite crystals cut perpendicularly to the optical axis at 1.3 μm wavelength. The aftereffect is associated with nucleation and expansion of oppositely magnetized domains that occur in a monodomain sample after removal of an external magnetic field. Magnetization reversal processes are visualized in a Faraday setup and studied by measuring the temporal dependence of the state of polarization of a transmitted light beam.
