Abstract

The ab-plane magnetic penetration depth λ in c-axis-oriented YBaCuO thin films was estimated from the inductance measurements. The temperature dependence of A was shown to be consistent with the Bardeen-Cooper-Schrieffer (BCS) theory under the local limit condition. It was also shown that the experimentally obtained relationship among δ(T=0), the resistivity p and the critical temperature T was consistent with the theoretical one obtained from the local limit BCS theory. From that relationship, the value of λ(T=0) could be deduced from p and Tc Moreover, the critical current was studied from the bias current dependence of X.
