在NbSe_2、CeRu_2、URu_2Si_2和UPd_2Al_3的正常态和超导混合态中都观察到了de Haas-van Alphen(dHvA)振荡。的dHvA的频率,这是成比例的费米面的极端横截面积,不改变正常和混合状态之间的幅度。对于f-电子超导体,混合态的回旋有效质量减小,相应的传导电子的丁格尔温度或散射率增加。从混合态dHvA振幅的角度依赖关系讨论了URu 2Si 2和UPd 2Al 3的线节点各向异性能隙。
The de Haas–van Alphen (dHvA) oscillation was observed clearly in both the normal and superconducting mixed states in NbSe2, CeRu2, URu2Si2, and UPd2Al3. The dHvA frequency, which is proportional to the extremal cross-sectional area of the Fermi surface, does not change in magnitude between the normal and mixed states. For the f-electron superconductors, the cyclotron effective mass is found to be reduced and the corresponding Dingle temperature or scattering rate of the conduction electron increases in the mixed state. An anisotropic energy gap with a line node for URu2Si2 and UPd2Al3 is discussed from the angular dependence of the dHvA amplitude in the mixed state.
