Mechanism of the de Haas-van Alphen oscillations in the superconducting
(National High Magnetic Field Laboratory, Tallahassee, Florida and Landau
Institute for Theoretical Physics, Moscow)
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.
