Application of a new formulation of Gor'kov's theory to clean type II superconductors

Abstract

The explicit free energy functional derived from Gor'kov's theory in a previous paper is shown to reduce, in special cases, to the free energies of the Meissner state, the mixed state, the nonlocal theory, and of the Ginzburg-Landau theory. For superconductors with small magnetization the free energy for arbitrary structure of the flux line lattice is given, for the first time, for the entire temperature range. For isotropic materials the triangular lattice turns out to be the stable one. The shear modulusc66of the triangular flux line lattice nearHc2is obtained for arbitrary temperature.
