Another focus is on nano-patterned hybrid superconducting/ferromagnetic systems where novel vortex dynamics can arise through magnetic vortex pinning and jamming with the goal to tailor the vortex liquid state in high temperature superconductors.

Argonne’s Materials Science Division is also involved in an ongoing EFRC program on vortex matter and critical current with Brookhaven National Laboratory and the University of Illinois at Urbana-Champaign, pursuing novel directions for enhancing the current carrying capability of commercial high temperature superconducting wires utilizing particle irradiation experiments with large scale time dependent Ginzburg-Landau simulations to pursue a new paradigm of critical-current-by-design.
