• uniaxial pressure
• anisotropy
• flux transformer
• superconductivity

By applying uniaxial pressures on Bi-2212 single crystals we have changed their interplanar spacing in order to understand which is the influence of anisotropy on the dynamics of vortex lines. We have performed transport measurements using the DC flux transformer configuration, applying uniaxial pressures and a magnetic field parallel to the c-axis of the sample. Our results indicate that the correlation length in the c direction can be effectively increased with pressure, modifying the nature of vortices in the liquid state.
