Abstract

The temperature dependence of the inter-plane complex conductivity σ_1c - iσ_2c of a-axis oriented YBa₂Cu₃O_7-δ thin films deposited on LaSrGaO₄(100) substrates has been measured in the millimeter-wave region by using a Mach-Zehnder type interferometric spectrometer. The value of σ_1c(T) increases just below T_c with decreasing temperature as well as the in-plane conductivity σ_1ab(T). The increase of σ_1c(T) below T_c is due to the strong suppression of the quasi-particle damping. The value of σ_2c(T) increases almost linearly with decreasing temperature. The temperature dependence of the magnetic penetration depth λ_c is deduced from the measured complex conductivity. It is found that λ_c^-2(T) changes almost linearly with temperature. The linear behavior of λ_c^-2(T) is consistent with the theory in which d-wave superconducting layers are coupled through normal layers.
