    Abstract
  • A series of NiSiB films of various thickness were prepared by R.F.sputtering.The films were annealed at different temperature and for different time.The resistance of the annealed films were measured as a function of temperature during two or more heating cooling cycles.Measurements of annealed films showed that there were two forms of resistance versus temperature curves.One was reversible the other was irreversible.The resistance of the thicker films (>1000) increased with increasing temperature and the resistance of thinner films (<400) decreased with an increase in the temperature.The temperature coefficient of resistance may be positive or negative.From the relaxation of amorphous material these behaviours are disscussed based on the activation energy spectra and in terms of extatended Ziman theory for metallic glasses.
