Essay

The thesis is devoted to the establishment of general laws in the electrophysical, magnetoresistive and magneto-optical properties of film systems based on Fe, Ni and Ag or Au, obtained by the methods of simultaneous and layer-by-layer condensation of metals, in conditions of size and concentration effects. For the first time, the concentration dependences of magnetoresistance, the thermal resistance coefficient and the strain coefficient for Fe, Ni, Ag or Au film systems in a wide range at the concentrations from 2 to 85 at.% of noble metal atoms were obtained. It was shown that the maximum MR (1,5–2,5%) and the minimum – TCR (0,8–1,0) 10–3 K–1 are observed at concentrations of noble metal atoms from 65 to 70 at.%, which suggests the possibility of the practical application of such film materials as temperature-stable elements of magnetic field sensors
