Description

The effects of vortex localization at columnar defects on the linear and non-linear dissipation in Tl2Ba2CaCu2O8 films are studied. The confinement of vortices into columnar defects leads to a minimum in the angular dependence of linear resistivity when the external field is brought into alignment with the defects. This observation provides compelling evidence for non-zero line tension of vortices in this highly anisotropic cuprate. The electric field vs current density (E-J) isotherms, and the temperature dependence of linear resistivity, both, indicate a Bose glass type of phase transition in this system
