Abstract

Silver pressure contacts were attached to very small two-phase whiskers of BiSrCaCuO and four-probe c-axis resistive transitions were measured. On cooling down, the high-Tc phase shows up as an increase in resistance followed by the usual drop to zero resistance of the dominant low-Tc phase. A model calculation, which scales the highly anisotropic whisker into an isotropic normal material with a superconducting sheet inclusion at various locations, reproduces the essential results.
