HIGH FIELD CHARACTERISTICS OF Nb3(Al, Ge)

Abstract
The Jc vs H curve for Nb3(Al0.8Ge0.2) was measured and compared with that of the binary compound Nb3Al. The Nb–Al–Ge alloy curve had a ``peak'' and its resistive critical magnetic field, Hr(J = 0), was above 220 kG at 4.2°K. The composition of the ternary alloy was determined and found to be closer to the ideal 3:1 atomic ratio than that of the binary alloy.
