| Abstract: | We report on concentration- and temperature-dependent specific heat measurements of (DyxY1−x)Co2 in the temperature range from 1.5 to 60 K in comparison with recent results of (HoxY1−x)Co2. The magnetic contribution to the specific heat, Cm, is analysed with regard to the appearance of spin-fluctuations and in terms of spin-glass phenomena. The loss of magnetic entropy in the dilute RE-concentration range indicates presumably an instability of the RE-moments. |
