| Abstract: | The specific heat from 1.2 to 23 K has been measured on a new high Tc superconductor, A-15 Nb3Si. The sample was prepared by explosive compression and has an onset of bulk superconductivity at 18.0 K, with a transition width of 0.7 K. The density of states for pure A-15 Nb3Si implied from the specific heat data is 0.94 ± 0.20 states/eV-atom, ΔC/γ Tc is 2.0 ± 0.2. |
