Abstract

In this research, the effect of different substitution quantities of zinc cations on electromagnetic and Microwave Absorption properties of Z-type barium hexaferrite with chemical composition of Ba3Co2-xZnxFe24O41 (x=0, 1. 2, 1. 3, 1. 4, 1. 5, 2) generated by high energy Milling method was studied. X-ray diffraction (XRD) method was used to verify the formation of Z type Ba-hexaferrite phase in the synthesis conditions. Magnetization properties of different compositions were studied by alternative gradient force magnetometery (AGFM). X-ray diffraction (XRD) method was used to confirm the formation of Z-type Ba-hexaferrite phase. The investigations by AGFM showed that the amount of magnetization increased by substituting the desired composition. So that the amount of magnetization (67 emu/g) for an unsubstituted sample will reach its maximum (84 emu/g) for the sample with composition of o Zn Fe O. In addition, complex Permeability and Permittivity coefficients of the samples were studied by vector network analyzer (VNA). Using the measured coefficients, reflection loss curves were plotted. The results of the reflection loss (RL) plots showed that, on average, the maximum absorption bandwidth occurred among the samples at a frequency range of 4-8 GHz. The best absorption (the most negative reflectance loss) was observed at-47 dB and at a frequency of 7 GHz for the sample with an index of substitution of x=1. 3.
