Abstract
M-type barium hexaferrites synthesis with Zn-Mn doping ion (BaFe) to be applied as a microwave absorbent material using co-precipitation method. The materials used in the synthesis process are FeCl3, 12M HCl, NH4OH 37%, CoCl2.6H212-2x CoO and NiClO. This research to investigate the effect of doping ion concentration variation (x = 0.0, 0.6 and 1.0) and calcination temperature (T = 80, 600, and 800oC) on electrical properties. The samples were characterized using Network Vector Analyzer (VNA). The result from VNA showed that the electrical conductivity values measured in the range 8.0-15.0 GHz indicate that the sample is a semiconductor (5.8 x 10-4 - 1.27 x 10-1 S/cm). The value of permittivity real and imaginary showed that increased with increasing of concentration doping and frequency.
