Investigation of Structural and Dielectric Properties of Double Perovskite Ho2NiMnO6 Compound

Abstract

The fascinating and diverse properties of double perovskites (DP) materials have attracted attention due to electrical, magnetic and structural properties. Due to their potential for usage in capacitive devices, memory devices, tuneable microwave filters, and other devices, the DP recently gained a lot of scientific interest. It is well known that these compounds demonstrate magnetoresistance and magnetocapacitance near ambient temperature. The DP compound (Ho2NiMnO6(HNMO) was prepared by conventional solid-state reaction method. The X-ray diffraction (XRD) analysis confirms the structure is monoclinic with the space group P21/n. The phase formation was further verified via FTIR spectral studies. FESEM was employed to investigate the morphology of the sample. Frequency-dependent dielectric constant, dielectric loss and conductivity were investigated at room temperature from 1000[Formula: see text]Hz to 1[Formula: see text]MHz.
