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.

通过低能离子注入调整BiFeO3的多铁性

摘要:本文介绍了注入Au+、as +、Ge+、Y+和Co+等多种离子来改变BiFeO3 (BFO)陶瓷的结构参数、表面形貌和多铁性能。所有样品均采用固相反应法合成。在~ 3 × 1012个离子/cm2的500 keV离子注入下，BFO的结构、形态、铁电性和铁磁性发生了显著变化。x射线衍射图显示植入样品的结构畸变。扫描电镜(SEM)图像显示，由于质量输运，表面晶粒尺寸发生了明显的变化。x射线光子光谱(XPS)显示了所有离子的成功注入，并揭示了辐照样品中Fe2+/Fe3+浓度的影响。磁环和铁电环显示，由于植入，BFO的铁电/铁磁性能得到了改善。

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.
