摘要：

The specific heat of an amorphous Dy-Cu alloy includes a large linear contribution ( gamma equals 155 mJ/mole K**2) at temperatures well below the sharp spin-freezing transition at T//f equals 18 K. This can be simply explained in terms of single-ion excitations of a Kramers ion interacting with a random oriented crystal field and a weaker magnetic field.
