· JVASP-104953· KBaFe4As4

KBaFe4As4 is an iron-based pnictide compound belonging to the family of high-temperature superconductors discovered in the late 2000s. This is an experimental research material rather than an established commercial alloy, studied primarily for its superconducting properties and potential to understand unconventional superconductivity mechanisms in iron-based systems. While not yet deployed in production applications, this material family is of significant interest to the superconductivity research community and represents a potential pathway toward next-generation superconducting materials for power transmission, magnetic imaging, and particle acceleration applications.
