Generalized London theory of the mixed state of high-κ superconductors as a projection of the quasiclassical Eilenberger approach

► The quasiclassical Eilenberger equations were solved in the mixed state of high-κ SCs. ► The distribution of the magnetic field is calculated self-consistently. ► Comparison with different analytical nonlocal linear approaches is done. ► The results can be used for analysis of the μSR experimental data.
