Abstract
This work presents the implantation of various ions, such as Au

(BFO) ceramics. All the samples were synthesized using the solid-state reaction method. Significant variations in the structural, morphological, ferroelectric, and ferromagnetic properties of BFO were observed due to the implantation of various ions using 500 keV at ion fluence of ~ 3 × 10

. X-ray diffractometer patterns showed structural distortion in the implanted samples. Scanning Electron Microscopy (SEM) images exhibited definite grain size variation over the surface due to mass transport. The X-ray Photon Spectroscopy (XPS) indicated the successful implantation of all ions and revealed the impact of Fe

concentrations in irradiated samples. The magnetic and ferroelectric loops revealed the improved ferroelectric/ferromagnetic behaviour of BFO due to implantations.
