Abstract

Multi functional composite materials based on BaZn2Fe16O27 (BZF) ferrite and antimony-doped tin oxide (the mole ratio of Sb/Sn is 1:5) composite were prepared by co-precipitation method. The structure, morphology, and property of the composites are characterized using X-ray diffraction, scanning electron microscopy, UV–visible spectroscopy, and a network analyzer. The results showed that nano ATO particles were formed on the surface of flake ferrite. Upon the addition of ATO particles, the complex permittivity of the BZF/ATO composites increases, while the complex permeability of the BZF/ATO composites increases firstly, and then decreases. The reflection loss varies with the change of the BZF/ATO mole ratio, even more the reflection loss peak changes. At 2.7 mm thickness, the reflection loss of the BZF/ATO composites with a mole ratio of 1:1 reaches the maximum value −58.91 dB at 8.08 GHz, and the bandwidth over an absorptivity of 90 % (−10 dB reflection loss) is 9.28 GHz (ranging from 6.32 to 15.6 GHz). The 1.06 μm laser reflection of BZF/ATO composites decreases to a minimum 4.662 %, when the mole ratio of BZF/ATO is 2:1.
