Abstract
We develop a quasiclassical approach to the energy spectrum of an anisotropic superconductor in a magnetic field, B, such that Hc1≪B≪Hc2. Low temperature de Haas–van Alphen oscillations are considered for two cases: (1) the extremal electron orbit may coincide with a symmetry line and (2) the orbit crosses points where the superconducting order parameter has zeros. The signal is shown to be small in both cases.
