iron-based superconductors

Iron-based superconductors are a class of materials that can conduct electricity without resistance at relatively high temperatures compared to traditional superconductors. They are composed mainly of iron combined with other elements like arsenic or chalcogens. Their unusual ability to become superconducting is tied to complex electronic and magnetic interactions within their layered structures. Researchers are interested in these materials because understanding them may lead to new, practical applications such as more efficient power transmission, magnetic sensors, and advanced electronic devices, all while operating at more feasible temperatures than conventional superconductors.
