Abstract

We utilize the microstrip resonator technique to measure with very high sensitivity the magnetic penetration depth in thin film samples of Nb, NbCN and YBa₂Cu₃O_7-δ. The penetration depth data for the low-T_c superconductors can be fit very well to a single-gap BCS temperature dependence using measured parameters. The temperature dependence of the YBa₂Cu₃O_7-δ data cannot be fit to a single-gap BCS temperature dependence, but may require a multiple gap fit.
