Altering Electrical Features of LuFeO3 Compound Via Ir Doping into Fe Sites

Three ceramic compounds, LuFeO3, LuFe0.95Ir0.05O3, and LuFe0.90Ir0.10O3, were fabricated via using solid-state reaction technique. Scanning electron microscopy (SEM) analyses have shown the porous nature of the samples. The loss-tan(δ) of Ir substituted compounds are less than the undoped sample at...

description Three ceramic compounds, LuFeO3, LuFe0.95Ir0.05O3, and LuFe0.90Ir0.10O3, were fabricated via using solid-state reaction technique. Scanning electron microscopy (SEM) analyses have shown the porous nature of the samples. The loss-tan(δ) of Ir substituted compounds are less than the undoped sample at frequencies > 105 Hz. The impedance study has revealed the Ir substituted samples have higher impedance values. Z″ and M″ vs frequency plots unveiled the existence of a non-Debye relaxation with short-range migration of carriers in the examined compounds. It has been shown 5 mol % Ir substituted specimen holds the maximum resistivity at 100 0C. Scanning electron microscopy has been utilized to study surface morphology.
