摘要：

Properties of magnetic field penetration depth-lambda in c-axis-oriented YBaCuO thin films were studied from inductance measurements. It was shown that the temperature dependence of lambda 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-lambda(0), resistivity-rho and critical temperature T(c) in YBaCuO films was shown to be consistent with that obtained for conventional superconductors. By using that relationship, lambda(0) could be deduced from rho and T(c) of the film.
