Mechanism of the de Haas-van Alphen oscillations in the superconducting mixed state

Abstract:  For the vortex lattice in an anisotropic superconductor with well-separated cores (Hc1<<B<<Hc2), it is shown that sizable de Haas-van Alphen oscillations are caused by the levels crossing of the energy threshold separating localized and extended states of excitations moving in the average magnetic field B.
