#ThrowbackThursday 1960's: Niobium Germanium (Nb3Ge)–23K Superconductivity (1967-1974) With AFOSR sponsorship, Niobium Germanium (Nb3Ge) was discovered to be a superconductor in 1973, and for 13 years (until the discovery in 1986 of the cuprate superconductors) it held the record as having the highest critical temperature. Primary investigators D. W. Deis, John R. Gavaler, and W. T. Reynolds, published their findings in June 1974 in AFOSR Technical Report 74-0989, while working at Westinghouse Research Labs., Pittsburgh, Pa. In an April 2012 IEEE/CSC & ESAS European Superconductivity News Forum article, on the history of superconductivity research at Westinghouse, AFOSR was singled out for its support in this area. The authors noted that: “Special credit is also due to one government agency, the AFOSR. Since the late 1960s it maintained continuity of support for the relatively fundamental work in materials – until the group was sold to Northrop Grumman and even beyond. This was due to the long-term vision of the late Program Director Max Swerdlow (1915 - 1989) and his successor Harold Weinstock.” #BasicResearch #tbt #superconductivity #MaterialsScience
