文摘

Calorimetric and shear modulus measurements on bulk glassy Pd₄₀Ni₄₀P₂₀ are performed. The obtained data is used for the calculation of structural relaxation-induced heat flow within the framework of the Interstitialcy theory. A good correspondence between the calculated and experimental heat release and absorption both below and above T_g is found. It is concluded that a description based on the population of 鈥渄efect鈥?states that are similar to dumbbell interstitials is capable to correctly describe the observed heat flow.
