“…It has been shown earlier that, as the thickness of the film increases, the permeability spectra differ more and more from the gyromagnetic model. [13][14][15] As a first interpretation, it was noticed that above the so-called critical thickness, stripe domains form due to the presence of a ͑small͒ growth-induced perpendicular anisotropy. 11 The micromagnetic calculation of magnetization dynamics in such a structure indeed showed several peaks, related to different regions, that reproduced the experimental permeability spectra.…”

The static and dynamic magnetic properties of samples consisting of two soft magnetic layers with in-plane easy axes at right angles are studied by micromagnetics and experiments. A one-dimensional micromagnetic model is developed, and solved quasianalytically for statics and dynamics. In particular, it is shown that the magnetic permeability arises from a set of eigenmodes, each with a macrospin ͑or gyromagnetic͒ response, that are excited differently depending on ac field orientation. Experiments ͑magnetization curves, permeability under field and in several directions͒ on cobalt-based amorphous alloy bilayers are well reproduced by the model with a single set of parameters. Such samples are therefore model one-dimensional nonuniform magnetic systems, simple yet with a rich behavior, for statics and dynamics.

“…For this reason, thin-film material mainly composed by Fe and Co based material have attracted many investigate [1][2][3][4]. FeCoBSiO 2 materials not only have saturation magnetization, but also we can increase the resistivity by accommodating the content of the Si and O element, which reduce eddy lose and increase the resonance frequency.…”

The microstructure and electromagnetic properties of FeCoB-SiO 2 thin films which were deposited on different substrates (silicon, glass and Mylar) by using magnetron sputtering were studied. X-Ray Diffraction revealed that FeCo nanocrystalline only precipitated in FeCoB-SiO 2 thin films on silicon and glass substrates, and the FeCoB-SiO 2 films on Mylar substrate were amorphous. The surface images obtained by atomic microscopy (AFM) indicated that films on Mylar substrate with biggest particle size (about 120-150 nm), and agglomerated particle was discovered. The static electromagnetic properties, including resistivity and saturation magnetization for the films on different substrates, had also been investigated. The films sputtered on glass showed highest resistivity (2140 .cm) and a biggest saturation magnetization (4 π Ms = 13 kG).
