“…The designer and developers of modern electronic devices seek small-size, lightweight, high-speed, and cost-effective devices. High anisotropy field, saturation magnetization, and high resistivity are prerequisites properties for those soft magnetic thin films [2] [3]. Fe-metalloid amorphous alloy demonstrated excellent soft magnetic such as high permeability, low coercivity, and lower core loss, thereby lacking grain boundary in the amorphous phase and magnetocrystalline anisotropy field [4] [5].…”

In this work, we investigated the influence of phosphorus and magnetic anneal on the soft magnetic properties of electrodeposited FeMnP alloy films prepared by changing sodium hypophosphite concentrations. X-ray diffraction radiation patterns showed an amorphous structure of electrodeposited alloy films. The saturation magnetization and coercivity value decreased from 586 emu/cc to 346 emu/cc, and 52 Oe to 18 Oe, with the P content increased, respectively. The absorption resonance peak became broad as the P content increased, and the natural resonance frequency decreased from 1.8 GHz to 0.6 GHz, with the P content increasing. Magnetic annealing of samples reduced the magnetic damping, and natural resonance frequency increased by about 1.8 GHz and 3.5 GHz for the sample with lower and higher P content. The film structure with lower P content changed at 300˚C, while the structure remains unchanged for the films with higher P content. Thus, the crystallization temperature could depend on the P content in the film. FeMnP alloy films could be used in high-frequency devices.

A broadband coplanar waveguide method, recognized as a simple and effective broadband permeability measurement tool, was used to measure the frequency dependent permeability of various magnetic thin films. It was revealed that measured permeability was strongly dependent on the dimension of the films and the geometry of the waveguide. This dependency was proven to result from the confinement of magnetic fields in the films by LLG equation. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

In order to break through the conductive percolation threshold limitation of the conventional granular films to increase resistivity (ρ), while keeping large complex permeability (μ̃), a series of compositionally graded FeCoB-SiO2 granular films with different multilayer structures were deposited on flexible substrates. The high-frequency electromagnetic properties were investigated. The experimental results showed that the compositionally graded granular films had obvious in-plane uniaxial magnetic anisotropy and the coercivity in the easy axis (Hce) was as low as 3.97 Oe. Both the ρ (∼15.4 mΩ·cm) and μ̃ (μi'=276.3 and μ″max=441.4) of the compositionally graded FeCoB-SiO2 granular films were simultaneously higher than those of the conventional FeCoB-SiO2 granular films. Two resonance peaks of complex permeability spectrum were also observed.
