| Annotation | The results of the study magnetoresistive properties (magnetoresistance) and Kerr effect (Kerr rotation angle versus magnetic field, coercive and magnetization) of three- and four-layer films Au(3)/Co(20)/Fe(70)/S, Au(3)/Co(3)/Au(6)/Fe(20)/S, Au(3)/Fe(20)/Au(6)/Co(3)/S, Au(3)/Fe(3)/Au(6)/Co(20)/S and Au(3)/Co(20)/Au(6)/Fe(3)/S (іn parentheses indicate the thickness in nm), which was condensed in vacuum 10 – 8 Pa on single-crystal (100) MgO and amorphous SiO2/Si substrates. It is established that the film systems implemented anisotropic ferromagnetic resistance with an amplitude from 0.1-0.2 % to 0.5-0.7 %. Based on Kerr measurements was established that the value coercive varies from a few mT to 40 mT. Films on substrates with a (100)MgO with two-axis anisotropy, and on the SiO2/Si – uniaxial magnetic anisotropy. |
