Résumé
Nous avons mesuré la chaleur spécifique des échantillons de Cu Mn avec des concentrations comprises entre 102 et 104 at. ppm. A basse température, la chaleur spécifique magnétique est donnée par ΔC = AT+BT2 avec A indépendant de concentration.


Abstract
We have measured the heat capacity of samples of -Mn with concentrations between 102 and 104 at.ppm. At low temperatures the magnetic heat capacity is given by ΔC = AT+BT2 with A independent of concentration. The entropy associated with the spin system is Rln5.
