Abstract

Quasiparticle excitations in the mixed state of a type-II superconductor outside the vortex cores are shown to fall into bands, and near Hc2 have a Landau-level type of structure. This leads to de Haas–van Alphen oscillations in the quasiparticle magnetization. Most of the pairing comes from states near the band edges and gives rise to a complicated structure of the order parameter.
