计算了自旋轨道相互作用下传导电子的磁化率。该模型是由于沃尔夫假设两个带分开的一个小的能隙。计算表明，由于磁场的带间效应，当费米能级位于带隙区时，磁化率对抗磁性有较大贡献。这一结果适用于铋，并提出了可能的解释其磁性的有效价数和各向异性的原因的依赖。
The magnetic susceptibility of conduction electrons in the presence of spin-orbit interaction is calculated. The model is that due to Wolff which assumes two bands separated by a small energy gap. Our calculation shows that due to the interband effect of the magnetic field the susceptibility has a large contribution to diamagnetism when the Fermi energy lies in the band gap region. This result is applied to bismuth, and possible interpretations are proposed for the dependence of its magnetic property on the effective valence number and the cause of the anisotropy.
