Abstract
The microwave dissipation induced by the interaction of AC magnetic field with the vortex system is reported for the first time in a Bi-2223 compound. It is the third high anisotropy compound, in addition to Bi-2212 and the organic superconductor κ(ET2)Cu(NCS)2+, where similar microwave dissipations were observed. It confirms that intrinsic Josephson coupling is necessary to induce this interaction. Intercalation of less than 2% of Bi-2212 and Bi-2202 phases in this single crystal results in the formation of different regions in the crystal with Tc's ranging from 110 K to 80 K, where only a very small part could be assigned to stoichiometric Bi-2223. Comparison of the results with a high quality optimally-doped Bi-2212 compound shows that the presence of the different regions in the Bi-2223 single crystal, affects the distribution of the PV and JV.
