Evidence
Gavaler, Appl. Phys. Lett. 23, 480 (1973): sputtered Nb3Ge films with an onset near 23 K; subsequent work locked the ambient-pressure A15 record at 23.2 K. Held the record from 1973 until the cuprates. Replicated A15 intermetallic.Rank 08 of 8

Evidence
Matthias, Geballe, Geller, Corenzwit, Phys. Rev. 95, 1435 (1954): superconductivity in Nb3Sn near 18 K. Modern wire-grade Nb3Sn is quoted at 18.0–18.3 K ambient. Still the workhorse A15 conductor for high-field magnets.Try another pair
