用自洽APW法计算了铁磁性fe3o4在高温立方相中的能带结构。虽然所得的能带结构与离子Neel模型非常接近，但表明流动电子模型比局域电子模型更合适。B位铁的少数自旋e带在\( \varGamma \)点处有一个电子费米面，在W点附近有空穴面。实验数据包括光电子发射、光学反射率、中子散射和输运现象，并与计算的能带结构进行了定性讨论。
Band structure of the ferrimagnetic Fe 3 O 4 was calculated in the high temperature cubic phase by means of self-consistent APW method. Though the obtained band structure corresponds closely with the ionic Neel model, it was shown that the itinerant electron model is more adequate than the localized electron model. The minority spin d e bands of B site iron have an electron Fermi surface at the \( \varGamma \) point and hole surfaces around the W point. Experimental data including photoelectron emission, optical reflectivity, neutron scattering and transport phenomena were discussed qualitatively in relation to the calculated band structure.
