Abstract
The highly anisotropic properties of the superconducting Bi2Sr2CaCu2O y (BSCCO) were studied by a cavity perturbation technique with the microwave magnetic and electric fields, which were parallel or perpendicular to the CuO2 planes. Through careful measurements and analysis, we succeeded in obtaining the quantitatively reliable results of microwave conductivity σ1 and penetration depth λ both in the ab-plane and along the c-axis, except the detailed behavior of σ c1 in the superconducting state. Temperature evolution of λ2(0)/λ2(T) was found to be quite anisotropic, suggesting that the quasiparticle conduction remained to be anisotropic even in the superconducting state.
