Аннотация:Magnetic, magnetooptical properties and FMR spectra of the multilayer films (Ni81Fe19)/Ag have been investigated. These properties are found to have a non-monotone behaviour in relation to the thickness of the non-magnetic layer of Ag caused by the changes of the character of exchange interaction between magnetic permalloy layers. The films with antiferromagnetic exchange (t = 11, 12, 13 Angstrom) exhibit non-linear hysteresis loops, decrease of the magnetooptical transversal Kerr effect (TKE) magnitude and additional FMR lines.
