Tailoring the multiferroic properties of BiFeO3 by low energy ions implantation
Abstract
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 ~ 3 × 1012 ions/cm2. 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.
期刊介绍：
While ceramics have traditionally been admired for their mechanical, chemical and thermal stability, their unique electrical, optical and magnetic properties have become of increasing importance in many key technologies including communications, energy conversion and storage, electronics and automation. Electroceramics benefit greatly from their versatility in properties including:
-insulating to metallic and fast ion conductivity
-piezo-, ferro-, and pyro-electricity
-electro- and nonlinear optical properties
-feromagnetism.
When combined with thermal, mechanical, and chemical stability, these properties often render them the materials of choice.
The Journal of Electroceramics is dedicated to providing a forum of discussion cutting across issues in electrical, optical, and magnetic ceramics. Driven by the need for miniaturization, cost, and enhanced functionality, the field of electroceramics is growing rapidly in many new directions. The Journal encourages discussions of resultant trends concerning silicon-electroceramic integration, nanotechnology, ceramic-polymer composites, grain boundary and defect engineering, etc.
