| 英文摘要 | The increase in electromagnetic wave pollution at high frequency (gigahertz band) has led to an increasing demand for more effective microwave absorption materials (MAMs). This study aims to investigate magneto-crystalline anisotropy materials as MAMs. Magnetic and microwave absorption properties of Y2Co17-xFex (x = 0, 5, 9, 13, 17) are reported in this study. As the Fe content increases, the magneto-crystalline anisotropy of Y2Co17-xFex changes from planar anisotropy to axis, then to cone, and eventually to plane. Meanwhile, the variation trend of the magnetization (M-s) value increases first and then decreases, reaching a maximum at x = 9. The Y2Co17-xFex/paraffin composites (x = 0, 13, 17) with the planar anisotropy show stronger reflection loss (RL) than that composite (x = 5) with the uniaxial anisotropy. The strongest RL value is achieved for the conical anisotropy composites (x = 9). This composite, with conical anisotropy and highest M-s, exhibits the highest gigahertz frequency permeability, which is advantageous for improving the impedance matching and attenuation abilities of microwave absorption. The Y2Co8Fe9/paraffin composite exhibits a reflection loss value of - 46.9 dB and effective absorption bandwidth (EAB, RL < - 10 dB) of 4.74 GHz with a thickness of 2.0 mm at 10.2 GHz, suggesting its applicability as an efficient microwave absorbent in the gigahertz frequency. |
