A research team headed by Yanwei Ma, a scientist at the Institute of Electrical Engineering at the Chinese Academy of Sciences, has introduced a novel strategy for creating high-density flux pinning centers leveraging asymmetric stress fields. This innovative approach markedly enhances the current-carrying capacity of iron-based superconducting wires under intense magnetic fields. The team utilized a large-scale extrusion forming technique to harmoniously manage hydrostatic pressure and shear stress, thereby generating a high density of dislocations. Subsequent to optimized heat treatment, these dislocations were arranged in an orderly fashion, forming an efficient flux pinning network that significantly boosts the flux pinning force.
