c-axis superfluid response and quasiparticle conductivity in Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} and Bi{sub 2}Sr{sub 2}CuO{sub 6+{delta}}

Josephson plasma resonance for underdoped Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} and Bi{sub 2}Sr{sub 2}CuO{sub 6{delta}}have been measured by sweeping the microwave frequency continuously. The resonance enables one to determine the superfluid density and quasiparticle conductivity in the c-axis accurately. They show that the superfluid response and the low energy excitations of the condensate in the c-axis of these materials are very different from those in the ordinary Josephson multilayer tunnel junctions. The Josephson coupling energy in single layer Bi{sub 2}Sr{sub 2}CuO{sub 6+{delta}}is more than 5,000 times smaller than is predicted in interlayer tunneling model.
