Abstract
The problem of transformation of the quasiclassical Eilenberger theory to the one-parameter London model is considered for the mixed state of clean type-II superconductors. Numerical computations demonstrate that introduction of a field dependent coherence length ξh(B) is enough for description of the magnetic field distribution in the vortex core of a superconductor. It is found that the shape of ξh(B) has strong temperature dependence. The comparison between s- and d-wave pairing symmetry is done. Different behavior of ξh(B) in triangular and square vortex lattices is found.
