N2 - Thermodynamics and vortex lattices of low-κ type-II superconductors are studied numerically within the Eilenberger equations of superconductivity. Below some critical value κc(T) of the Ginzburg-Landau parameter κ = λ/ξ, there is a first-order transition at H c1 (type-IIa superconductivity) as a consequence of attractive vortex-vortex interaction. For κ > κc the phase transition is of the second order (type-lib superconductivity). The phase boundary κc(T) that separates type-IIa and lib superconductivity is calculated.
