“…Therefore, compared with the samples without ball milling, the ball milled samples have better high-frequency magnetic properties and microwave absorption properties. [26] The degree of plane orientation (DPO) is an important parameter to determine whether a magnetic material has an easy-plane magnetocrystalline anisotropy. Its formula is [12]…”

“…In civil industries, microwave absorbing materials are widely used to solve the problems of electromagnetic pollution and interference caused by electronic equipment and electronic communication. [1][2][3][4][5][6] Microwave absorbing materials can be classified as dielectric absorbing materials and magnetic absorbing materials. Compared with dielectric materials, it is easier to achieve impedance matching with magnetic materials, and their matching thickness is thinner, so they have become popular absorbing materials.…”

The easy-plane anisotropy of Y2Co17 rare earth soft magnetic alloy has high saturation magnetization, operating frequency, and good impedance matching. Therefore, it is expected to become a kind of high-performance microwave absorbing material. In this paper, Y2Co17 alloy was prepared by reduction-diffusion method, and its micro powder was prepared as polyurethane (PU) based composite absorbing materials (Y2Co17/PU composites). The microwave properties of composites with different volume fractions are calculated. The composites showed outstanding absorption characteristics in the range of 20-30 vol%, and the minimum reflection loss (RL) was less than -50 dB. When the volume fraction was 25%, the effective absorption bandwidth can cover the X-band at a thickness of 1.5 mm, and the Ku-band at a thickness of 1.08 mm. The absorption mechanism was analyzed by the interface reflection model. The RL absorption peak bandwidth mechanism was discussed by using the amplitude relation, and calculating the effective absorption bandwidth at different thicknesses. The effective absorption bandwidth values were in good agreement with the theoretical expectation.

“…Alloys produced by the melt-spinning method have better physical, chemical and mechanical properties than those obtained by the conventional methods [17,18]. The melt-spun Sm-doped FeSiCo was reported in our previous study [19]. Co is a magnetic metal and is relatively stable, whereas Al is a non-magnetic metal and unstable.…”

The flaky Sm1-xFexSiAl ( x = 0,1,2) alloy powders were prepared by melt-spun technique with a wheel speed of 30 m s−1, followed by ball milling method. The flake-shaped FeSiAl alloy particles with the average particle size range from 5µm to 40µm were obtained. The XRD spectra show that the single α-Fe phase without other intermediate phase can be detected for all samples. Complex permittivity decreased remarkable VS complex permeability decreased somewhat with increasing Si content. With the thickness of 1.8 mm, the minimum Reflection Loss (RLmin) of Fe70Si20Al10 alloy powder is −3.4 dB at 2 GHz, while that of Sm2Fe68Si20Al10 alloy powder is −5.8 dB at 3.8 GHz. It is found that the Sm-doped FeSiAl composites can be potential microwave absorbing materials.
