摘要: Abstract The structural properties and relaxation processes of magnetization in [Ni 81 Fe 19 ( t 1 )/Ru( 2 )] N superlattices =number bilayers) were analyzed by ferromagnetic resonance (FMR) with a fixed microwave frequency. One series samples was deposited constant NiFe layer thickness ) variable Ru ); the other series, . A single FMR mode observed for >75 A it has been attributed to exchange-coupled layers across interlayers. For values , several modes appeared they associated non-coupled magnetic phases different effective formed during multilayer growth. linewidths as function strong dependence on −2 observed. It contribution two-magnon scattering mechanism linewidth.
