Superconductivity is being widely applied in advanced technology programs, such as nuclear fusion reactor, superconducting power generators and energy storage, MRI - diagnosis, and magnetically levitated vehicles. High performance multifilamentary wires such as NbTi, (Nb, Ti) 3Sn, V3Ga and Nb3Al are being developed. High - Tc superconducting materials such as YBaCuO, BiSrCaCuO, and TlBaCaCuO have attracted a great interest in regard to the basic properties and potential applications in liquid nitrogen. Even though many problems still remain to be solved, remarkable progress is being achieved and some new applications are being offered. The development of the high - Tc materials will lead to a complete reassessment of superconducting technologies.
