The Low-temperature Specific Heats of Y₂(Co₁₋ₓAlₓ)₁₇ Alloys
The specific heats of Y2(Co1-xAlx) 17 alloys were measured in the temperature range 1.8-19.5 K for x=0, 0.08, and 0.12. The data below 11 K are well described by C= γT+βT3. Values of γ and β for the three samples were obtained. No evidence for a T3/2 term existed. This is not surprising due to the high Curie temperatures. The increase in the value of γ from alloying is significantly higher than that calculated by assuming a rigid-band model ignoring volume-change effects.
