Characterization of Mn0.8Zn0.2Fe2O4 synthesized by flash combustion technique

Mn0.8Zn0.2Fe2O4 was prepared by flash combustion technique. The ferrite powder prepared by this technique was calcined at 900 °C. The uniaxially pressed samples were sintered at a temperature of 1340 °C in controlled atmosphere. The magnetic initial permeability, AC electrical resistivity were studied as the function of frequency in the range 1 kHz to 13 MHz and temperature up to 300 °C. The dielectric constant and dielectric loss were also studied as the function of frequency.
