摘要
理论计算表明,在含Ni钡铁氧体中出现大磁光偏转的主要原因不是奇宇称晶场的作用,而是由于基组态和激发组态间的电偶极跃迁造成的。
The calculation of the Faraday rotation in the Ni-substituted Ba ferrite based on the quantum theory is presented. The Faraday rotations is contributed mainly by the intra-ionic eletrical dipole transitions between the 3d^8 and 3d^7 4p configurations. Therefore, the d-d transitions induced by the odd-parity crystalfield can not explain the megneto-optical resonance phenomenon of the Ni^(2+) ions in BaM.
