摘要：

The angular dependence of the flux flow resistivity rho(THETA,T,H) in T12Ba2CaCU2O8 is measured as the external field is brought into alignment with heavy-ion-irradiation-induced columnar defects. A flux lock-in state, manifested as a minimum in the rho(THETA,T,H) data, evolves as the system is cooled deeper into the mixed state. This observation provides compelling evidence for nonzero line tension of vortices in this highly anisotropic superconductor. The temperature dependence of the flux flow resistivity at perfect alignment is consistent with Bose glass theory of vortex localization at columnar defects.
