摘要：

The ab-plane magnetic penetration depth lambda in taxis -oriented YBaCuO thin films was estimated from the 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 rho and the critical temperature T-C was consistent with the theoretical one obtained from the lambda(T=0) limit BCS theory. From that relationship, the value of lambda(T=0) could be deduced from rho and T-C. Moreover, the critical current was studied from the bias current dependence of lambda.
