Ferromagnetic resonance studies in Co/SiO2 multilayers

The uniaxial in-plane and out-of-plane anisotropies of [Co/SiO2] 10 multilayers have been studied by ferromagnetic resonance, magnetometry and transmission electron microscopy. The surface and volume anisotropy constants are in the range of values typical for multilayers with Co and transition metals of the iron group. The influence of the intermixed Co–SiO2 region is discussed. # 2007 Elsevier...

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 force microscopy on microscopic cobalt single layer films

We report mechanical detection of ferromagnetic resonance ~FMR! signals from microscopic Co single layer thin films using a magnetic resonance force microscope ~MRFM!. Variations in the magnetic anisotropy field and the inhomogeneity of were clearly observed in the FMR spectra of microscopic Co thin films 500 and 1000 Å thick and ;403200 mm in lateral extent. This demonstrates the important pot...

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...
