Abstract:
We report on study of the vortex liquid in Pb-doped Bi-2223 single crystal using the in-plane resistivity measurements as a function of temperature and magnetic field up to 6T applied perpendicular to CuO planes. Below $T_c$ at the upper part of superconducting transition we found Arrhenius-like resistivity behavior. With further temperature decrease close to onset of dissipation resistivity shows power law dependence on temperature signaling approaching vortex-glass transition. The critical exponents $\nu(z-1)=4.6\pm0.5$ are found to be field independent within experimental errors. We also present magnetic phase diagram defining region of nonzero critical current for Pb-doped Bi-2223 single crystal.
