A way to increase the critical current in high temperature superconductors: neutron irradiation

摘要

Neutron irradiation is a promising method for a spectacular enhancement of the critical current density of the high temperature superconductors. The suppression of the mechanisms responsible for superconductivity under irradiation are analyzed and put side by side with the effects on the flux line lattice dynamics. Additionally, the evolution of the creation/generation balance of the defects of the crystal structure is connected to the evolution of the response of the vortex system with an emphasis on the ceramic materials.
