Abstract:
We report measurement of the ab-plane resistivity in Y-doped
Bi2Sr2CaCu2Oy crystals, A trend of resistivity saturation is clearly
observed for samples with high Y concentrations. This trend is not
affected by annealing treatment. We analysed the data in terms of Drude
model. The metallic resistivity beyond the Ioffe-Regel limit suggests a
''small'' Fermi surface in the heavily Y-doped samples.
