Tailoring the multiferroic properties of BiFeO3 by low energy ions implantation

This work presents the implantation of various ions, such as Au+, As+, Ge+, Y+, and Co+, to modify the structural parameters, surface morphology, and multiferroic properties of BiFeO3 (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 similar to 3 x 10(12) ions/cm(2). 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 Fe2+/Fe3+ concentrations in irradiated samples. The magnetic and ferroelectric loops revealed the improved ferroelectric/ferromagnetic behaviour of BFO due to implantations.

Automated summary

The work conducted implantation of various ions into BiFeO3 ceramics, resulting in significant changes in structural, morphological, ferroelectric, and ferromagnetic properties.
