The structural-phase state and magnetoresistive properties of three-layer film systems based on Ni and V and Ni and Au or Ag total thickness d = 25-55 nm thick steel spacer ds = 5 nm. Experimentally tested the influence of annealing temperatures from 300 to 600-700 K and the total thickness of the sample on the value and nature of the magnetoresistive magnetoresistance dependencies. Established that the annealing temperature range in said film system Ni/Ag/Ni retain negative isotropic magnetoresistance, samples of Ni/Au/Ni with anisotropic magnetoresistance and magnetoresistance film system Ni/V/Ni is very sensitive to changes in the overall thickness of the sample is can be as isotropic and anisotropic magnetoresistance so.
