Spin-wave resonance frequency in a multi-layer film

“…The transfer matrix approach has been applied to the calculation of the energy and relative intensities of SWR spectra as a function of the spacer thickness. Various pinning conditions at the external surfaces have been considered and the role of interface anisotropy have been discussed in detail [13]. The FMR spectra of sputtered Fe/Ti multilayers were obtained as a function of orientation of 4 the applied magnetic field from in-plane to out-of-plane and were fitted theoretically to determine the magnetic anisotropy.…”

“…It is valuable to develop some quantum methods to study the microwave properties of magnetic multilayer films. According to earlier work, the microwave properties of a magnetic multilayer thin film are significantly affected by magnetic surface anisotropies [13,25,27,28], interface anisotropies [13,24,25,26], interfacial couplings [24,25,26] and an external magnetic field [14,25,28]. Therefore, our present proposal is to utilize the linear spin-wave approach and Green's function technique to study the SWR frequency (including FMR frequency) in a ferromagnetic multilayer thin film with single-ion surface, interface and bulk anisotropies.…”
