· LiFeAs

LiFeAs is an iron-based pnictide compound that belongs to the family of iron-based superconductors, a class of materials discovered in the late 2000s as alternatives to copper-oxide superconductors. This material is primarily of scientific and research interest rather than established industrial production, with investigations focused on understanding its superconducting mechanisms and potential for high-field applications where conventional superconductors face limitations.
