Investigation of structural, magnetic, and ferroelectric properties in one-dimensional rare-earth dysprosium orthoferrite (DyFeO₃) nanofibers

In this article, one-dimensional Dysprosium orthoferrite (DyFeO₃) nanofibers was synthesized via electrospinning and analyzed their structural, morphological, elemental, magnetic, dielectric, ferroelectric and leakage current properties at room temperature. XRD confirmed a stable orthorhombic structure with a Pnma space group, while SEM images displayed a smooth, one-dimensional morphology with a diameter of 130 nm. The nanofibers exhibited a dielectric constant of 326 at 100 Hz. Magnetic studies demonstrated antiferromagnetic ordering with a saturation magnetization of 5.06 emu/g. Furthermore, investigation confirmed the ferroelectric behavior with a saturation polarization of 1.56 μC/cm². The nanofibers demonstrated an energy storage capacity of 8.35 mJ/cm³ with an efficiency of 52.36 %.
