Sažetak
We report the results of a study of electrical resistivity and of the superconducting transition temperature, T (sub c) in hydrogen-doped Zr-Co metallic glasses. The increase of the room-temperature resistivity and its temperature coefficient are explained as a consequence of increased disorder due to hydrogen doping. The temperature dependence of the resistivity has been analysed using theoretical models of weak-localisation and electron-electron interaction in disordered three-dimensional conductors. Hydrogen dopant lowers T(sub c) and broadens the superconducting transition region. We discuss the effect of different hydrogen environments on T (sub c).
