摘要：

The Ba(3)Co(2-x)MgsFe(24)O(41) hexaferrites were prepared by the sol-gel combustion route. The materials were annealed at 1350 degrees C and displayed the single-phase characteristics. X ray density (D-x) decreases owing to increasing Mg concentration. Crystallite size was calculated with the help of Debye Scherrer's formula and found within the 17-18 nm range. Fourier transform infrared spectroscopy was used to determine the specific absorption peaks of hexagonal ferrites. It was executed in the region of 420 700 cm(-1)-the occupancy of Mg2+ ions at the octahedral site at delayed alternation of Fe3+ ions. As a result, the dielectric permittivity decreased. The grain boundary contribution was clearly seen in synthesized ferrites' cole plots. The cole - cole plots show a single semi-circle which reveals that grain boundaries play a significant role in the conduction process. Magnetic measurement indicated the ferrimagnetic behavior of all samples.
