该理论是超交换理论的扩展，包括了自旋-轨道耦合的影响。在整个计算过程中使用了安德森最近发展的一种新的形式主义。定域在阳离子上的单电子态用Wannier函数表示，单电子哈密顿量由定域态的能量和它们之间的转移项组成。我们将位于位置B的两个简并波函数表示如下：(r-R)，4(r-R)，N4
The theory is an extension of the superexchange theory to include the effect of spin-orbit coupling. A new formalism recently developed by Anderson'is used throughout the calculation. The oneelectron states localized on the cations are ex-pressed by Wannierfunctions and the one-electron Hamiltonian consists ofthe energy of the local-ized states and the transfer terms among them. We denote the two degenerate wave functions localized at the position B as follows:(r-R), 4 (r-R), n4
