Abstract
Superconducting and magnetic properties in the ${\mathrm{La}}_{3}$Tl-${\mathrm{Pr}}_{3}$Tl system are discussed. Superconductivity persists up to very high Pr concentrations, ${\mathrm{Pr}}^{3+}$ being in a crystal-field-singlet ground state. The Van Vleck susceptibility per ${\mathrm{Pr}}^{3+}$ ion at $T=0$ increases with increasing Pr concentration, indicating ferromagnetic exchange coupling between the Pr ions. At concentrations higher than 93-at.% Pr the system becomes ferromagnetic. No current theoretical model accounts for the observed magnetic behavior.
