Annotation The results of the study of giant magnetoresistance in film systems Ag / array of ferrite nanoparticles / Ag and graphene / array of ferrite nanoparticles / graphene, which were formed by means of spin-coating or Langmuir-Blodgett technique, are represented. In systems of the first type during annealing the magnetoresistance value is changed within 3-20 %, and in the systems of the second type – 3 %. It is established that the optimum Ag film thickness, where magnetoresistance MR = 2 %, has a value of 5 nm.
