Abstract

Technological developments are inflection points in our life. One of such technologies driving developments is superconductor technologies. This technology is candidate to revolutionize many aspects of our life due to its attractive properties. One of the most important properties is Zero-DC electrical resistivity. In superconductor applications, zero electrical resistivity (infinite electrical conductivity) is utilized. The most significant figure of merit for superconductors is critical temperature, Tc. Below the critical temperature, material exhibits superconductive behaviour; at temperatures upper than Tc, material behaves as non-superconductive. Scientists are in race to discover materials having Tc as high as possible in order to utilize it in room-temperature level and reduce the cooling power consumption as much as possible. This work proposes a method to determine Tc of superconductors wisely and strongly. In this work, other determination methods are compared. Beside of Tc determination, a new figure of merit for superconductors is introduced. Scientists in race are encouraged to search materials having not only high or even ultra high critical temperature but also high stability and high quality factor. Also, introduced term will determine performance of future superconductor applications.
