✦ Synopsis

Thermophysical parameters of glassy systems strongly depend on their thermodynamic state. A high value of the specific heat of the "as-quenched" samples is caused by the anharmonicity of the interatomic potential. The thermal diffusivity is influenced through microstresses which are induced by production. The ribbon is inhomogeneous from the thermodynamic point of view in the period after production. This inhomogeneity vanishes through "ageing" or heat treatment.
