The results of experimental investigations of the structure and phase states, electrophysical and magnetoresistance properties of the two-component film systems based on Co and Cu or Ag, Fe and Cr or Cu are presented. The choice of the mentioned systems is due to different structure and phase states stabilized within them: solid solution (Fe- and Cu- or Cr-based systems) and granular solid solution (Co- and Cu- or Ag-based systems). Experimental results for thermal resistance coefficient (TRC) agree satisfactory or well with relations for TRC of film alloy or granular alloy. It serves as an additional argument contributing to the conclusions about the structure and phase state of two-component systems. Magnetoresistance (MR) study is performed in three measuring geometries. The analysis of influence of the thermal annealing on MR, saturation field, sensitivity to the magnetic field is carried out.

Keywords: structural and phase state, solid solution, granular alloy, thermal resistance coefficient, magnetoresistance.
