摘要：
In order to understand the intrinsic properties of high abundance permanent magnet materials, effects of Co element on the structure, magnetic, and microwave absorption properties of La-12.5(Fe1-xCox)(81.3)B-6.2 alloys have been investigated with x = 0, 0.1, 0.2, 0.3. The X-ray diffraction results revealed that compounds of La-12.5(Fe1-xCox)(81.3)B-6.2 crystallized the Nd2Fe14B-type structure with the space group P42/mnm. The saturation magnetization of the powders increases with the Co content increasing, 97.7 emu/g for x = 0.3. The minimum absorption peak value of La-12.5(Fe1-xCox)(81.3)B-6.2 alloy reaches about - 18.69 dB at 10.56 GHz with the matching thickness of 2.5 mm.
