Abstract

London penetration depth λ_L was calculated for superconductors having lifetime broadened density of states. With the increase of gap states, λ_L increases and the temperature dependence deviates from the ordinary form. The model gives a T² dependence of λ_L in the case of weak-coupling limit of the Bardeen-Cooper-Schrieffer theory. The results are discussed referring to some experimental results of magnetic field penetration depth of oxide superconductors.
