Magnetoresistive(MR)effect in the magnetic films are giving rise to vast application capacities for the super-high density information storage. Recently, much attention has been paid to the magnetoresistive granular(or heterogeneous)alloy films such as Co-Ag system. In this paper, we carried out studies of structural, magnetic properties and magnetoresistance of as-deposited and annealed magnetic granular Co_xAg_<100-x> alloy films prepared by rf cathode sputtering method with x varied between 12÷40 in some various technological conditions. The structure of these films was investigated by X-ray Diffraction(XRD), Atomic Force Microscopy(AFM), Electron Diffraction(ED)and Transmission Electron Microscopy(TEM)methods. Magnetic properties were measured using Vibrating Sample Magnetometer(VSM)and MR effect was detected with a conventional four-poing probe resistance measurement at room temperature in magnetic fields up to 14 kOe. Relations of the structural and magnetic properties with MR effect were discussed. Some of influence of technological conditions on MR were considered.
