摘要：The interaction between vortex and crystal lattice (periodic arrays of flux quantum and atoms) in type-II superconductors is evaluated through Ginzburg-Landau theory. It is found that, in an isotropic crystal, the magneto-elastic coupling energy counteracts the elasticity-driven intervortex interaction energy. Thus, the elastic response is induced entirely by individual vortices taken separately. Furthermore, the strain in a vortexlattice cell decays quadratically with the distance from the vortex core, which allows for a cutoff at the cell boundary. Finally, it could be concluded that if the jump in the elastic constant at Hc2 is comparable to unity, the elasticity energy dominates the competition between the vortex lattice and crystal elasticity. This effect likely results in the second magnetization peak in the reversible magnetization.
