最近对磁反射和de Haas-van Alphen效应的测量，使热解石墨能带参数的测定更为精确。原则上，这些实验可以为石墨中微小的自旋轨道相互作用提供更直接的测量。这种相互作用提升了E3带的简并性，沿着沿着带边缘的任何地方，并在点K附近产生带隙，这可以从磁反射实验的分析中推导出来。当H点能带的简并度被提升时，得到两个极值费米表面积，从而预言了两个低频de Haas-van Alphen振荡。
Abstract Recent measurements of the magnetoreflection and of the de Haas-van Alphen effect have made possible a more accurate determination of the band parameters of pyrolytic graphite. In principle, these experiments could provide a more direct measurement of the small spin-orbit interaction in graphite. This interaction lifts the degeneracy of the E3 bands everywhere along the zone edge and gives rise to a band gap near point K which could be deduced from analysis of the magnetoreflection experiment. When the degeneracy of the energy bands at point H is lifted, two extremal Fermi surface areas are obtained, thus predicting two low frequency de Haas-van Alphen oscillations.
