The unique properties of BFT are attributed to its multiferroic behavior, i.e., the ability to exhibit both magnetic and ferroelectric ordering simultaneously. However, the utility of BFT is limited by its low magnetization, which is due to its highly insulating nature. To overcome this limitation, various approaches have been employed, including doping B-site ions, which can modify the magnetic and electrical properties of BFT. Among the various B-site dopants, boron (B) has been reported to enhance the magnetization of BFT. However, the effect of B-doping on the other properties of BFT is still not well understood. In this study, we aim to investigate the effect of B-doping on the structural, magnetic, and electrical properties of BFT iron films.Objectives:The main objectives of this study are:1. To synthesize Bi5FeTi3O15 iron films using the sol-gel method.2. To prepare B-doped Bi5FeTi3O15 iron films using the same method.3. To characterize the structural properties of the synthesized iron films using X-ray diffraction (XRD) and scanning electron microscopy (SEM).4. To investigate the effect of B-doping on the magnetic properties of the iron films using a vibrating sample magnetometer (VSM).5. To measure the electrical resistivity and dielectric properties of the B-doped iron films using impedance spectroscopy (IS).精品文档---下载后可任意编辑Methods:The Bi5FeTi3O15 iron films will be synthesized using the sol-gel method.
