摘要：
Faraday rotation measurements were performed on a Ho0.7Y2.3Fe5O12 single crystal at 77 K and B parallel-to [111] in ultrahigh pulsed magnetic fields (up to 350 T). Several anomalies of the rotation were observed in the 15-50 T region, but only a slight increase of the magnitude of the Faraday effect was found above 150 T. A model is proposed to interpret the results, taking into account both the para- and diamagnetic contributions of rare earth and ferrous subsystems.
