Ferromagnetic resonance modes in single and coupled layers with oblique anisotropy axis - art. no. 174410

Ferromagnetic resonance (FMR) modes in thin films with oblique anisotropy a xis are investigated. In such films, the anisotropy axis is tilted from the normal with a tilt angle delta. The equivalent magnetic field of such an a nisotropy is derived. The mode position (resonant field) H-R, the linewidth DeltaH, and the peak intensity have been calculated. The effect of the til t angle on these parameters is discussed. The FMR modes of two coupled ferr omagnetic thin films with oblique anisotropy axes have also been studied. A nalytical expressions for the resonance condition have been found for stron g ferromagnetic and antiferromagnetic coupling.
