Abstract

MgB₂ is a known superconductor material competing with the commercially popular low-temperature superconductor of Nb–Ti. The key advantages of MgB₂ include a relatively high transition temperature of 40 K, low material cost, and large upper critical field, with potential in various superconducting applications in a cryogen-free environment. This review will summarize the state-of-the-art MgB₂ various conductors fabricated by Sam Dong Co., Ltd., Republic of Korea and provide clear insights to practical users.
