Abstract
Correlation between the crystal lattice and the vortex lattice in anisotropic (uniaxial) type-II superconductors due to magnetoelastic interactions is studied theoretically. Within the strain-dependent Ginzburg-Landau model, the energy of the magnetoelastic interaction of the vortex lattice is evaluated with the ΔV effect (difference of specific volumes of normal and superconducting phase) as the main source of the elastic strain. For NbSe2 in tilted fields near the upper critical field Hc2, the vortex lattice is the same as obtained within the London model in fields well below Hc2 with magnetoelastic interactions taken into account.
