Abstract
We have measured the low temperature (from 0.1 K up to 5 K) specific heat and thermal conductivity of an amorphous ZrNi superconducting alloy "as sputtered" and after annealing. We observe a variation of the Debye temperature and of the thermal conductivity related to a structural relaxation caused by the annealing.
