The shear modulus of bulk amorphous Pd40Ni40P20 and its relation to viscosity and specific heat

We have measured the shear modulus and its temperature dependence of Pd40Ni40P20 using an EMAT technique. Measurements were made of the temperature dependence at constant heating rate of the infinite frequency shear modulus G. Values of the shear softening parameter gamma are estimated and compared with those obtainable from frequency dependent shear moduli, specific heat and viscosity measurements. There is overall agreement with the Interstitialcy Theory of Condensed Matter States.
