“Research Front of Superconductivity Towards the Discovery of Room-temperature Superconductor”

Prof. Yoshio Kitaoka, Associate Prof. Hidekazu Mukuda, Assistant Prof. Mitsuharu Yashima

　　“Superconductivity” - zero electrical resistance - was first discovered in 1911. Over the hundred years since then, many substances exhibiting superconductivity (SC) have been discovered. The upper right figure is a history of the discovery of superconducting materials and displays the increase in transition temperature (Tc) over that period. An unexpected breakthrough was the discovery of high-Tc SC in copper oxides in 1986. Soon after, Tc rose to 164 K in Hg-based compounds under press...
