抄録

Properties of magnetic field penetration depth λ in c-axis-oriented YBaCuO thin films were studied from inductance measurements. It was shown that the temperature dependence of λ was consistent with the local limit Bardeen-Cooper-Schrieffer (BCS) theory, and that the value of the London penetration depth was estimated to be 148 nm. Moreover, the relationship among zero-temperature penetration depth λ(0), resistivity ρ and critical temperature Tc in YBaCuO films was shown to be consistent with that obtained for conventional superconductors. By using that relationship, λ(0) could be deduced from ρ and Tc of the film.
