Abstract
The structure of the vortex lattice in anisotropic superconductors at an ar bitrary temperature in magnetic fields close to critical was studied. Gener ally, a rhombohedral structure with a vertex angle depending on temperature , magnetic field, and material constants is formed. An important factor is the small (2%) difference of the free energies of the triangular and square lattices in the Ginzburg-Landau approximation. This factor also persists i n anisotropic superconductors. (C) 2001 MAIK "Nauka/ Interperiodica".
