Abstract

Multiferroic BiFeO₃ (BFO) and Dy doped Bi_1-xDy_xFeO₃ (BDFO) (where x= 0, 0.05, 0.1, 0.15, 0.2) samples were synthesized by solid state reaction method. The materials were subjected to a comprehensive structural analysis using X-ray Diffraction (XRD) technique, revealing a consistent perovskite structure across all samples. Further insight into the microstructural features and grain formation was obtained through Field Emission Scanning Electron Microscopy (FESEM), providing a detailed characterization of the morphology and structural integrity of the synthesized powders. Additionally, Energy Dispersive X-ray Analysis (EDAX) was employed to confirm the elemental composition of the samples, validating the presence of the Dopant (Dy) and ensuring the homogeneity of the materials. The dopant's influence on the overall elemental makeup was crucial in understanding the potential alterations in the physical properties of the materials. Moreover, the magnetic behavior of the samples was systematically investigated to discern the impact of Dy doping on the magnetic properties. Anomalies in the magnetic behavior were observed, and a comprehensive analysis was conducted to elucidate the underlying mechanisms responsible for these deviations. The findings not only contribute to the understanding of the multifunctional characteristics of these materials but also offer valuable insights for potential applications in the realm of advanced electronic and magnetic devices.
