Temperature impedance spectroscopy of composites of the system (1 - x) MgFe2O4 - xBaTiO3
Keywords:
ferrite-piezoelectric composite, electrical conductivity, activation energyAbstract
The results of study dielectric properties of ferrite-piezoelectric composites of (1 – x)MgFe2O4 – xBaTiO3 are given in the temperature range 293 – 723 K in the frequency range 10–2 – 106 Hz. According to the impedance spectra the dominant contribution of electrical conductivity on direct current is detected at T > 523 К. It is shown that the activation energy of conductivity σdc increases significantly with increasing temperature about 400 K for all composites.
