摘要
Mn0.8Zn0.2Fe2O4 was prepared by flash combustion technique. The ferrite powder prepared by this technique was calcined at 900degreesC. The uniaxially pressed samples were sintered at a temperature of 1340degreesC 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 300degreesC. The dielectric constant and dielectric loss were also studied as the function of frequency. (C) 2003 Elsevier B.V. All rights reserved.
