Resumen

Measurements of the critical temperature T_c (n, P) as a function of Ce concentration n and pressure P ≤ 20 kbar are reported for the reentrant superconductors (La_{1 - n}Ce_n)Al₂ and (La_0.8Th_0.2)_{1 - n}Ce_n. No evidencce was found for a third transition back to the superconducting state. Monte Carlo calculations including strong electron-phonon coupling may explain our experiments, although the effects of interimpurity interactions remain uncertain.
