Pinning of Abrikosov vortices on dislocations and the critical current in high-temperature superconductors

摘要: The microscopic mechanisms for single-particle core pinning of quantum vortices on the insulating cores isolated dislocations are investigated both parallel and mutually tilted orientations vortex dislocation also an infinite periodic chain edge dislocations. theoretical results consistent with experiment in regard to temperature orientation dependences depinning critical current low magnetic fields, when interaction between is exponentially small, they predict strong anisotropy force along transverse chains
