Sereni, J. G., J. G. Huber, C. A. Luengo, and M. B. Maple. "Calorimetric study of the magnetization of Ce impurities in superconducting Th-Y and Th-Sc alloys." Journal of Low Temperature Physics 30, no. 5-6 (1978): 729–737.
Abstract: Specific heat measurements are reported in detail for the Ce impurity in the superconducting matrix systems Th65Sc35Ce, Th80Y20Ce, and Th65Y35Ce. The variation of the specific heat jump DeltaC at the superconducting transition temperature T c is indicative of the magnetic nature of an impurity. For Th65Y35Ce a departure is found from the BCS law of corresponding states predicted for a nonmagnetic impurity. This departure is correlated with that observed for (La, Th)Ce systems and related to DeltaT c/n (initial slope of T c vs. n) and Ce effective size (implied by lattice parameter data).

Abstract: Direct measurements of the surface superconducting magnetization of the PbTl system shows that this state is a thermodynamic reversible one.
