摘要：

BaFe12-xCOxO19 (BFCO, x <= 0.4) ceramics with superior magnetic and electromagnetic (EM) properties were prepared using Co3+ substituted BaFe12O19 (BFO) in 2.6-18 GHz. Compared with the ceramics without Co3+, the incorporation of 40 mol% Co3+ enhances magnetic properties; the saturation magnetization (M-S) is improved by about 55.6 emu.g(-1) due to the variety of magnetocrystalline anisotropy. The resonance behaviors of complex permeability are observed and resonance frequency shifts to lower frequency range from 6 to 3 GHz. The minimum reflection loss (RL) of - 32.1 dB ( < -10 dB) is obtained at 11.2 GHz in 8.5-13.5 GHz at 2.0 mm thickness in the sample with x = 0.4, which suggests that such ceramics is highly promising as effective microwave absorbers for EM applications.
