“…Similarly, Dong et al. improved the electromagnetic performance of BaZn 2 Fe 16 ‐ x Ta x O 27 by doping with high‐valence Ta 5+ ions 13 . It is believed that the introduction of high‐valent metal ions can enhance the exchange coupling between Fe 3+ and Fe 2+ ions, thereby improving the electromagnetic properties of materials.…”

With the advancement of electrical and electronic devices, overcoming electromagnetic pollution turns into an urgent problem. In this work, high‐valence molybdenum (Mo6+) was doped into M‐type hexagonal barium ferrite (BaFe12‐xMoxO19) to improve its electromagnetic performance. The relationship between the Mo6+ doping concentration and the crystallographic structure, morphology and electromagnetic properties was studied in detail. Structural characterizations authenticate that the Mo6+ ions prefer the 2b site, increasing the lattice values and grain size, and boosting more Fe3+ conversion into Fe2+. The magnetic hysteresis loops demonstrate a reduction of saturation magnetization and coercivity values with the increase of Mo6+ concentration. While the microwave absorption properties were obviously improved by the doping Mo6+, and obtained the highest RLmin value of ‐56.12 dB@16.1GHz and effective absorption bandwidth of 4.2 GHz at x = 0.1, displaying a potential role in absorbing material.This article is protected by copyright.
