temperature to 300 °C with the heating rate of 10 °C/min and maintained at this temperature for 3 hours. Then, the samples were heated at the same rate to 700 °C and maintained at this temperature for next 5 hours. After completion of the calcination stage the nanocrystalline powders were cooled down freely.
For the iron doped series, the chelating agent: citric acid monohydrate (C 6 H 8 O 7 ·H 2 O) with ethylene glycol (99 % CHEMPUR) were added to the solution. The solutions were dried for several hours at 150 °C. The obtained powders were ground in an agate mortar and

M-type hexagonal ferrites with compositions SrFe (12-2x) Co x Ti x O 19 (x = 0.0, 0.3, 0.5, 0.7, 1.0), were synthesized by the conventional ceramic processing method. The detailed procedure of the synthesis has been published in our previous paper  . The pellets were sintered in air at a temperature of 1300 °C for 12 hours in an electric furnace. Then the pellets were shaped to fit exactly into a 10.16 × 22.86 mm 2 rectangular X-band waveguide (WR-90). The complex scattering parameters that correspond to the reflection (S 11 or S 22 ) and transmission (S 21
