“…The coercivity first increases slightly from 20 to 26 Oe when t NiFe decreases from 120 to 80 Å, then decreases strongly to 5 Oe when t NiFe decreases to 20 Å, at 300 K. This decrease could be attributed to the change in the microstructure. The change of the coercive field is comparable to that resulting from the structural transition of the NiFe sublayers between the amorphous or nanocrystalline and polycrystalline states (see [10]). An additional contribution to the coercivity behavior could result from the interlayer exchange coupling of the NiFe sublayers across the Zr spacers.…”

Magnetic properties of NiFe/Zr multilayer films, prepared by DC magnetron sputtering, have been studied by vibrating sample magnetometer and ferromagnetic resonance (FMR). Spin-wave resonances were observed in Ni 81 Fe 19 /Zr multilayer films in FMR experiments, and the spin wave was found to be sustained by both the whole films. Estimated small interlayer coupling constant shows weak exchange coupling effect between NiFe layers across Zr spacers. The FMR linewidth, in parallel geometry, of the uniform mode was found to increase with decreasing NiFe thickness (20 Å ≤ t NiFe ≤ 120 Å) indicating that it corresponds to an interfacial effect. In addition, electronic and magnetic properties of multilayers are investigated by selfconsistent ab initio calculations based on Korringa-KohnRostocker (KKR). Spin polarized within the framework of the Coherent Potential Approximation (CPA) is considered for calculations.

“…In this work only the effect of the exchange interactions on the SWR modes of FePt thin films was considered, and both even and odd values were assigned to the spin-wave mode number n. The presence of even and odd SWR modes implies an inhomogeneous distribution of magnetization perpendicular to film plane, and an asymmetrical spin pinning (pinned or unpinned) at the surface and interface of the film [21,22]. It is important to note that the n ¼ 0 uniform mode can be excited in a film by the microwave field only when the magnetization is homogeneous and unpinned at both surface and interface of the film [23].…”

“…Given the above context, ferromagnetic/anti-ferromagnetic (FM/AF) thin films with a multilayer structure are considered as ideal candidates. The higher saturation magnetization (M s ), permeability (µ), and self-biased ferromagnetic resonance (FMR) frequency of the magnetic thin film make them suitable for high-frequency applications as nanostructured magnetic media and magnetic sensors [7][8][9][10][11][12][13]. Meanwhile, the multilayer structure has been widely used in giant magnetoresistance spin valves based on the exchange bias phenomenon.…”

This work demonstrates the dependence between magnetic properties and the thickness of NiFe thin films. More importantly, a quantitative study of the surface composition of NiFe thin film exposed to atmospheric conditions has been carried out employing angle-resolved X-ray photoelectron spectroscopy (ARXPS). In this study, we fabricated Ni81Fe19 (NiFe) thin films on Si (100) substrate using electron beam evaporation and investigated their surface morphologies, magnetic properties, and the thickness of the surface oxide layer. The coexistence of metallic and oxidized species on the surface are suggested by the depth profile of ARXPS spectra. The thickness of the oxidized species, including NiO, Ni(OH)2, Fe2O3, and Fe3O4, are also estimated based on the ARXPS results. This work provides an effective approach to clarify the surface composition, as well as the thickness of the oxide layer of the thin films.
