Measurement of the Electronic Specific Heats and the Debye Temperatures in Some Critical Metallic Alloy Glasses. Final Report

摘要

Specific heat measurements between approximately 1.5 and 4.2 exp 0 K are reported for four Pd-Si and three Pd-Si-Cu alloys. The compositions chosen for study covered the stable glass region in the Pd-Si-Cu system. Measurements were performed on relatively large samples (approximately 16 g) of spun amorphous ribbon. The electronic specific heat coefficient, gamma , is shown to be composition dependent, and to possess a maximum when presented as a function of the electron per atom concentration, e/a.
