Abstract
The impedance spectroscopy analysis for M-type BaFe12O19 (BaM) ceramics prepared by ceramic route is reported. The main aim is to investigate the electric properties in function of the synthesis parameters (milling time and milling power). It was shown that milling parameters strongly influence the electrical properties such as dielectric constant, whose magnitude increases with the milling power. Moreover the relaxation frequency is fully dependent on the milling parameters and it shifts to high frequencies when milling power decreases. Finally, impedance and dielectric loss tangent also change with milling parameters.
