Abstract
The general form of the temperature dependence of resistivity in metallic glassy alloys is discussed in detail using the results of the scaling model of localisation and models of electron-electron correlation effects. It is shown that for a metallic glass of relatively low resistivity there would normally exist a resistance minimum at low temperatures, while for glasses of higher resistivity the conductivity below theta D should be directly proportional to T, changing to a square root T dependence for higher temperatures. These predictions are then shown to be in accordance with new measurements on Cu50Ti50 and Ti50Be40Z10 alloys.
