【 摘 要 】

This research has been success in the synthesis of M-Barium hexaferrite (BaM) doping Co-Mn ions using coprecipitation method are expected to be applied as a base material in the coating RADAR. M-Barium hexaferrite (BaM) are BaFe12-2xCoxMnxO19synthesized with various concentrations (x = 0.0, 0.1, 0.2, 0.3) and the calcinations temperature (T = 400°C, 600°C, 800°C). The materials characterization using a X-Ray Diffraction (XRD), Transmission Electron Microscope (TEM), Inductance Capacitance and resistance (LCR) meter, and Vibrating Sample Magnetometer (VSM) Instruments. The measurement results using XRD shows the material has a hexagonal crystalline structure. The measurement results using a TEM show a sample of nano crystal materials with grain diameters up to 40 nm and spacing of the crystal lattice. The measurement results using a LCR-meter shows the electric conductivity of 1.15 × 10-6S/cm to BaM without doping, 3.75 × 10-6S/cm to 0.1 doping concentration calcination temperature of 400 °C, and 1,23 × 10-5S/cm to 0.3 doping concentration calcination temperature of 800 °C, thus including semiconductor materials. The magnetic properties of materials using a VSM test results show the value of coercivity of 0.1 T; remanence value of 0.06 emu/g; and the saturation value of 0.42 emu/g. The results above show BaM Co-Mn metal doping potential as anti-radar material.
