Abstract

The iron based superconductors have revealed distinctive superconducting properties, including reasonable critical temperature (Tc ≈ 56 K), extremely high upper critical field (Hc2) on the order of 100 T, high intrinsic pinning potential, low anisotropy values, generally between 1-8, high irreversibility field (Hirr), and high critical current density (Jc), which is of vital importance for low and high field application. Enhancement of Jc or flux pinning has always been an important focus of superconductor research over the past decade.
