Abstract
The interaction between wellseparated Abrikosov vortices is calculated using Eilenbergers version of the Gorkov theory Let λ and ξ be the decay lengths determining the asymptotic behavior of the magnetic field and the order parameter for an isolated vortex Then the onset of attraction in the limit of large vortex separation is either given by λ=ξ or by λ becoming complex whichever occurs first It is shown that in general a first order transition atHc1 takes place already in the region of asymptotic repulsion because of the appearance of a minimum in the interaction energy at finite vortex separation
