Magnetic, magnetooptical properties and FMR in multilayer films (Ni_81Fe_19) 10 A/Ag t

摘要

Magnetic, magnetooptical properties and FMR spectra of the multilayer films (Ni_81Fe_19)/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 changesof the character of exchange interaction between magnetic permalloy layers. The films with antiferromagnetic exchange (t=11,12,13 A) exhibit non-linear hysteresis loops, decrease of the magnetooptical transversal Kerr effect (TKE) magnitude and additional FM lines.
