Résumé
La résistance électrique de Pr dhcp a été mesurée entre 15 mK et 5 K dans la direction C. En-dessous de 0,4 K nous avons observé une contribution de type Kondo. L'ordre nucléaire, comme l'indique le temps de relaxation thermique, est observé vers 25 mK dans un cristal, mais paraît absent dans un autre.
Abstract
Electrical résistance of dhcp Pr has been measured between 15 mK and 5 K in the c-direction. Below 0.4 K a Kondo-like behaviour is observed. Coopérative ordering indicated by the thermal time constant, which has been observed near 25 mK in one crystal, seemed to be absent in the present sample.
