Which phenomenon explains superconductivity persistence, even with lattice defects?

💡 Explanation

Flux pinning traps magnetic flux lines at crystal defects. These impede vortex motion, maintaining zero resistance because pinned vortices cannot dissipate energy as heat; therefore flux pinning maintains superconductivity, rather than scattering which increases resistance.
