Abstract
M-type barium hexagonal ferrite (BaFe12O19) has been synthesized by sol-gel auto combustion method. The synthesized material was irradiated with 200 MeV Ag16+ ions using the 15UD Pelletron tandem accelerator and the changes in structural and surface morphology of material were investigated. The pristine (as-synthesised) and irradiated samples were characterized using different experimental techniques like x-ray diffraction (XRD), Fourier-transform infrared spectroscopy, transmission electron microscope (TEM) and vibrating sample magnetometer (VSM). The strong absorption peak between 580 and 440 cm−1 in the infrared spectrum and XRD confirmed the formation of ferrite structure for both irradiated and pristine samples. XRD peaks for the irradiated barium hexagonal ferrite were slightly broadened when compared pristine ferrite samples. The crystallite size of the irradiated barium hexagonal ferrite was higher than that of pristine barium hexagonal ferrite and is consistent with TEM images. Both saturation magnetization and coercivity were decreased with irradiation.
Highlights
Since last two decades, effects of Swift heavy ion irradiation on magnetic oxides and ferrites have been investigated to understand the modifications on their physical, magnetic and dielectric properties [1,2,3]
We synthesized M-type barium hexagonal ferrite (BaFe12O19) and to tune the structural and magnetic properties irradiated by swift heavy ion irradiation
The prepared barium hexagonal ferrite was irradiated with 200 MeV Ag16+ ions at a fluence of 1 × 1013 ions cm−2 using 15UD Pelletron Accelerator at New Delhi Inter University Accelerator Centre (IUAC), India
Summary
The synthesized material was irradiated with 200 MeV Ag16+ ions using the 15UD Pelletron attribution to the author(s) and the title of tandem accelerator and the changes in structural and surface morphology of material were the work, journal citation and DOI. The strong absorption peak between 580 and 440 cm−1 in the infrared spectrum and XRD confirmed the formation of ferrite structure for both irradiated and pristine samples. XRD peaks for the irradiated barium hexagonal ferrite were slightly broadened when compared pristine ferrite samples. The crystallite size of the irradiated barium hexagonal ferrite was higher than that of pristine barium hexagonal ferrite and is consistent with TEM images. Both saturation magnetization and coercivity were decreased with irradiation
