Abstract

We discuss the resistivity, the Hall effect, the Nernst effect, and the magnetization in the mixed state taking the motion of the Abrikosov and Josephson vortices into account. Measurements on a (BiPb)2Sr2Ca2Cu3O10 tape point out how the contribution of the Josephson vortices to the resistivity ρJ prevails at low temperatures and an analytical expression for ρJ is proposed. Above the irreversibility line the Hall effect, the Nernst effect, and the magnetization are less affected by the granularity of the material and, at first approximation, can be considered to be intrinsic properties. Starting from this assumption, we calculate the contribution of the Abrikosov vortices to the resistivity ρA using the Nernst effect and the reversible magnetization data. The ρA thus calculated has an order of magnitude close to the values reported in literature for single crystals, and shows an activated behavior with temperature, whose activation energy value is in strict agreement with that measured in epitaxial thin films of Bi(2223) compound.
