The stress caused by vortices in tetragonal superconductors contributes to the intervortex interaction which depends on vortex orientation within the crystal, on elastic moduli, and is attractive within certain angular regions even in fields along the c crystal axis. For sufficiently strong stress dependence of the critical temperature, this contribution may result in distortions of the hexagonal vortex lattice for H||c. In small fields it leads to formation of a square vortex lattice with a fixed H independent spacing. This should be seen in the magnetization M(H) as a discontinuous jump of magnetization at the transition from the Meissner to mixed states.
