The influence of surface pair breaking or pair formation on $\\lambda$ is described within the Ginzburg-Landau theory, with no model assumptions, for both strongly type-II and strongly type-I homogeneous superconductors. Generic values of $\\lambda$, which can differ greatly from the London penetration depth, are identified and demonstrated to be induced by large-scale inhomogeneities, wh","authors_text":"Yu. S.
