Large enhancement of superconducting transition temperature of SrBi3 induced by Na substitution for Sr
The Matthias rule, which is an empirical correlation between the superconducting transition temperature (T(c)) and the average number of valence electrons per atom (n) in alloys and intermetallic compounds, has been used in the past as a guiding principle to search for new superconductors with highe...
