Key words Two-layer film systems, Tensoresistive effect, Gauge factor, Strain and plastic deformation, Interface scattering.
The results of research strain deformation properties of thin films Ag, Co and two-layers films Ag/Co in the range of deformation Δεl = 0-1 % were presented. The plastic deformation in Co layer caused a similar deformation in the entire film system, even if the strain range Ag layer is not reached the limits of the transition elastic/plastic deformation. The increasing of gauge factor value of two-layer systems in comparison with thin films Ag and Co appears as a result of electron interface scattering.
