Dielectric characterization of the charge-ordered nickel oxides: La<sub>3/2</sub>Sr<sub>1/2</sub>NiO<sub>4</sub> and La<sub>5/3</sub>Sr<sub>1/3</sub>NiO<sub>4</sub>

Dielectric characterization of the charge-ordered nickel oxides: La<sub>3/2</sub>Sr<sub>1/2</sub>NiO<sub>4</sub> and La<sub>5/3</sub>Sr<sub>1/3</sub>NiO<sub>4</sub>

In this work, we study the dielectric properties of the layered perovskites La3/2Sr1/2NiO4 and La5/3Sr1/3NiO4 in the frequency range 20 Hz- 1 MHz and in the temperature range 110-350 K. For this study, we have synthesized single phase polycrystalline samples by a conventional solid-state reaction. T...
