In type‐II superconductors with uniaxial symmetry the three critical fields ( H c1 , H c2 , H c3 ) are calculated near the transition temperature T c using the anisotropic Ginzburg‐Landau equations. It is shown that in general an induced magnetic field δ H ⊥ perpendicular to the applied magnetic field exists and that the anisotropy removes the degeneracy in the direction of the flux‐line lattice. The pattern and the orientataion of the flux‐line lattice are in good agreement with the experimental results of technetium.
