Abstract
A series of glassy alloys of Zr xCu 1−x with x = 0.5 to 0.74 have been studied. Electrical resistivities, superconducting transition temperatures, upper critical magnetic fields and heat capacities have been measured. The specific heat values at low temperatures in the normal state can be described in the form C px = λ xT + β xT 3 without any higher powers of T. Debye temperatures, electronic densities of states and electron-phonon coupling constants have been evaluated from these measurements. As a quantity of the metastable glassy state the crystallization temperatures at constant heating rates have been determined by the first anomalies of the electrical resistances.
