Co effect on the structural, chemical and frequency depended electrical properties of YbFeO3 perovskite oxide compound

We have synthesized YbFe 1−x Co x O 3 (x = 0, 0.01, 0.05, 0.10) compounds by the conventional solid-state method. Structural and chemical analysis of the synthesized compounds have been carried out by XPS, SEM and EDX techniques. Frequency dependent (1–10 7  Hz) electrical properties including the l...

Zusammenfassung:We have synthesized YbFe 1−x Co x O 3 (x = 0, 0.01, 0.05, 0.10) compounds by the conventional solid-state method. Structural and chemical analysis of the synthesized compounds have been carried out by XPS, SEM and EDX techniques. Frequency dependent (1–10 7  Hz) electrical properties including the loss tangent, real and imaginary part of impedance and resistivity have been examined in wide range temperature (from − 100 to 100 °C with 20 °C step) using Dielectric/Impedance Spectrometer (Novocontrol). The frequency dependent loss tangent plots have showed different dielectric relaxations peaks and the activation energies of the compounds have been calculated from those peaks using Arrhenius relation. The resistivity measurement results revealed that the increasing Co doping ratio decreases the resistivity of the compounds.
