Abstract

The influence of nitriding on the static magnetic properties, electromagnetic parameters and microwave absorption properties of Y₂Fe₁₂Co₄Si alloy were investigated. The results demonstrated that nitriding improved the electromagnetic parameters and microwave absorption properties of the Y₂Fe₁₂Co₄Si alloy. The improvement of electromagnetic parameters is due to an increase in the Snoek limit and the polarization of the Y₂Fe₁₂Co₄Si alloy due to nitriding. The nitrided sample exhibits better impedance matching performance and electromagnetic loss capability due to its higher electromagnetic parameters. With a thickness of 1.23 mm, the maximum effective absorption bandwidth achieves 6.91 GHz (11.00–17.91 GHz), and the minimum reflection loss reaches –55.9 dB.
