Elastically Driven Ferromagnetic Resonance in Nickel Thin Films

Elastically driven ferromagnetic resonance in nickel thin films.

Surface acoustic waves (SAWs) in the GHz frequency range are exploited for the all-elastic excitation and detection of ferromagnetic resonance (FMR) in a ferromagnetic-ferroelectric (Ni/LiNbO(3)) hybrid device. We measure the SAW magnetotransmission at room temperature as a function of frequency, external magnetic field magnitude, and orientation. Our data are well described by a modified Landa...

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 ...

Junction of ferromagnetic thin films

In this paper, starting from the classical 3D micromagnetic energy, we determine, via an asymptotic analysis, the free energy of two joined ferromagnetic thin films. We distinguish different regimes depending on the limit of the ratio between the small thicknesses of the two films.
