Ferromagnetic resonance in Ag coupled Ni films

MAGNETOSTRICTION CONSTANT OF MULTILAYER Ni-Ag FILMS DETERMINED BY FERROMAGNETIC RESONANCE

The results of magnetostriction constant A, of multilayer Ni-Ag films are reported. The measurements have been performed at room temperature using strain modulated ferromagnetic resonance method. The magnetostriction constant As depends linearly on the inverse Ni layer thickness. This effect is suggested to be due to the reduced local symmetry in interfaces.

Ferromagnetic resonance linewidth in thin films coupled to NiO

The out-of-plane angular dependence of the ferromagnetic resonance linewidth, ∆H, has been measured for thin magnetic films coupled to NiO and for uncoupled control films. In the control films, ∆H is described by nearly angle-independent damping parameters. In the NiO-coupled films, however, the damping was found to depend strongly on magnetization orientation, with linewidth values comparable ...

Ferromagnetic resonance study of sputtered Co | Ni multilayers

We report on room temperature ferromagnetic resonance (FMR) studies of [t Co|2t Ni]×N sputtered films, where 0.1 ≤ t ≤ 0.6 nm. Two series of films were investigated: films with same number of Co|Ni bilayer repeats (N=12), and samples in which the overall magnetic layer thickness is kept constant at 3.6 nm (N=1.2/t). The FMR measurements were conducted with a high frequency broadband coplanar wa...
