$\text{Ab Initio}$ Study of Antisite Defects in Nb${}_3$Sn: Phase Diagram and Impact on Superconductivity

Nathan S. Sitaraman, Jared Carlson, Alden R. Pack +4

Antisite defects play a critical role in Nb${}_3$Sn superconducting radio frequency (SRF) cavity physics. Such defects are the primary form of disorder in Nb${}_3$Sn, and are responsib…
