摘要

The superconducting transition temperature for solid solutions of Gd, Pr, Yb, and Ce in lanthanum has been measured as a function of pressure up to approx 10 kbar. The transition temperatures for La+Gd with 0.6, 0.8, 1.0 and 1.2 at.% Gd, La+1 at% Yb, and La+1 at.% Pr, while depressed from that of pure lanthanum, exhibit positive pressure dependences similar to that observed for the double hexagonal close-packed (dhcp) phase of pure La, the values for the La+Pr and La+Yb being essentially the same.
