摘要：

The specific heat of Pd0.775Cu0.06Si0.165 alloys has been measured between 30 mK and 1 or 2K successively in glassy and polycrystalline phases obtained by annealing at 400 and 550 degrees C. Well defined T terms appear between 0.15 and 1K in each case, not very dependent upon the structure, but systematically higher in the glassy state. Below 80 mK, the specific heat is dominated by a hyperfine T-2 term, almost independent of the structure. This second point leads to the conclusion that the short-range order remains almost unchanged from the crystalline to the glassy states.
