摘要

The present study examines the electrical, magnetic, microstructural, and structural characteristics of the Bi1.8Pr0.2FeCrO6 compound produced through solid-state synthesis. The trigonal crystal structure with R-3c space group as the major phase is established by the Rietveld refinement of the XRD data. To validate the existence of Bi-O and Cr-O vibrational modes, Fourier transform infrared spectroscopy investigation has been performed. For the analysis of various vibrational modes, Raman scattering measurements have been employed. The microstructural characteristics by SEM images indicate that the grains are more compact and less porous. A wide range of temperatures (25-300 °C) as well as frequencies (1 kHz-1 MHz) were used to investigate and analyze the dielectric properties. Polarization vs. electric field hysteresis loop study (at room temperature) and magnetic analysis (at a variety of temperatures: 5 K, 100 K, and 300 K) confirm the multiferroic property of the sample.
