Characterization of Mn_(0.8)Zn_(0.2)Fe_2O_4 synthesized by flash combustion technique

摘要

Mn_(0.8)Zn_(0.2)Fe_2O_4 was prepared by flash combustion technique. The ferrite powder prepared by this technique was calcined at 900 ℃. The uniaxially pressed samples were sintered at a temperature of 1340 ℃ 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 ℃. The dielectric constant and dielectric loss were also studied as the function of frequency.
