Abstract

The complete temperature dependences of the in-plane and c^-axis microwave (10 GHz) penetration depth (T) and the surface resistance Rs(T) of high quality Bi2Sr2Ca1Cu2O8+ crystals are reported. In contrast to earlier measurements, a leading ab T dependence is observed at low temperatures, consistent with nodes in the in-plane gap. The overall behavior of ab(T) and Rsab(T) is similar to that of YBa2Cu3Oy at low T, but differs at temperatures near Tc. The c^-axis penetration depth c(T) is shown to best agree with a model of weakly coupled superconducting layers with nodes in the gap.
