Superconductivity of Hg3NbF6 and Hg3TaF6
Abstract
Low-temperature ac susceptibility measurements show that two new metallic compounds, Hg3TaF6 and Hg3NbF6, are superconductors with a critical temperature of 7.0 K. Critical fields are 20% higher in Hg3TaF6 but the temperature dependence of the critical field of the compounds is very similar down to 1.35 K. The critical field extrapolated to T=0 K is 0.17 T for Hg3TaF6 and 0.13 T for Hg3NbF6.
