- Abstract
The need to work on a low-dimensional and large specific surface is the modern need for the technology to serve scientific purposes. In this view, M-type Ba-based hexaferrite with rare earth doping has been synthesized in nano-fibrous form using the electrospinning method, by fixing the processing parameters such as voltage, flow rate, working distance, and differently concentrated doped hexaferrite, i.e., BaYxFe12-xO19, where x = 0, 0.3, and 0.5. An examination for the structural, microstructural, and magnetic behavior with the help of the X-ray diffraction technique (XRD), Fourier transform infrared spectroscopy (FTIR), vibrating sample magnetometer (VSM), and field emission scanning electron microscopy (FESEM) has been performed. All doped and un-doped fiber samples have a hexagonal phase having space group named P63/mmc as established through XRD results. FTIR results also confirm the chemical structure and stretching vibrations between the metal–oxygen complexes of all the samples. FESEM results have revealed no apparent change in the fiber diameter with doping concentration. The fiber specimen having x = 0.3 gives highest saturation and remnant magnetization of about 70.19 emu/g and 36.47 emu/g, correspondingly, followed by x = 0.0. Therefore, the fabricated materials with such excellent magnetic traits can become promising candidates in multifunctional applications, like recording media and the formation of permanent magnets.
