Abstract
The ab-plane magnetic penetration depth lambda in c-axis-oriented YBaCuO thin films was estimated from inductance measurements. The temperature dependence of lambda 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 lambda (T=0), the resistivity p, and the critical temperature T/sub c/ was consistent with the theoretical one obtained from the local limit BCS theory. From that relationship, the value of lambda (T=0) could be deduced from p and T/sub c/. Moreover, the critical current was studied on the basis of the bias current dependence of lambda .< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
