Amultilayer, [Ni(100nm)/Fe(100nm)]3has been investigated for the structure and low temperature resistivity. The resistivity increased with increase in temperature. The residual resistivity ratio (RRR) and the temperature coefficient of resistivity (TCR) were determined. The power law variations of resistivity with temperature were established. The contributions to resistivity for T above 80K are attributed to be predominant by electron-phonon and electron-magnon scatterings and for below 30K they are ascribed to be predominant by electron-electron and electron-defect scattering.
