According to traditional theory that Faraday rotation Angle was mainly due to the electric-dipole transition.

按照传统的理论，法拉第旋转角主要是由于电偶极跃迁所形成的。

So the conventional magneto-optical recording median, rare earth-transition metal (Re-Tm) alloys, is limited, because of its small Kerr rotation in the region of short wavelength.

因此传统的磁光记录介质-稀土金属与过渡组金属的合金就表现出局限性，因为这种材料在短波长范围的磁光效应很小。
