Study of Phase Formation and Electrical Properties of Double Perovskite Y2NiMnO6

Abstract

The double perovskite oxide Y2NiMnO6 has been synthesized using the conventional ceramic route. The crystal structure of the Y2NiMnO6 was confirmed to be monoclinic in the space group P21/c (14) through Rietveld refinement. The electrical properties have been studied in the frequency range of 20Hz - 2MHz and temperature range of RT - 600°C. The AC conductivity behavior of the sample shows a transition from an insulator/semiconductor to a metal-like material. Moreover, the material transitioned from positive to negative permittivity at 210°C. This transition is attributed to the change in electrical characteristics of the material from a capacitor to an inductor. © 2025 American Institute of Physics Inc.. All rights reserved.
