Abstract: The upper critical field Hc2 (T) of the A15 compound Nb100-xPtx (19 ≤ x ≤ 29.1) has been measured as a function of temperature T for various compositions and levels of irradiation with fast reactor neutrons. Compositions ranging from 19 to 29 at % Pt and neutron fluences up to 16 × 1018 n/cm2 (E > 1 Me V) were studied. A stoichiometric sample that had been rapidly quenched from the liquid ("splat-cooled") was also investigated. For the unirradiated samples, Tcexhibits a maximum of 10.4 K at the stoichiometric composition, while both Hc2 (0) and {Mathematical expression} attain their maximum values on the Pt-rich side of stoichiometry. The irradiated samples show a decrease of Hc2 (0) with increasing neutron fluence. The results are discussed in terms of antisite disorder and a strong correlation is obtained between decreasing Hc2 (0) and increasing disorder of the Nb atomic sites. © 1980 Plenum Publishing Corporation.
