| Abstract: | We have studied the influence of thickness, magnetic annealing temperature, and substrate material on a number of structurally sensitive magnetic and electrical properties of Fe15Co20Ni65 films. It is shown that the main microstructure parameter which determines the resistivity, its temperature coefficient, the anisotropy of the magnetoresistivity, the coercive force, and the induced magnetic anisotropy field is the crystallite dimension d. We establish the conditions for producing a structural state (d=10 nm) which, from a practical standpoint, has an optimal relationship between the magnetic and magnetoresistance properties.Physics and Applied Mathematics Scientific-Research Institute, Urals State University.
