- Abstract
The nanocrystalline Sr(1−x)CexFe12O19 (x = 0.00 < x < 0.09) strontium M-type hexaferrites (SrM-HFs) were prepared by self-propagation method using mixed fuels. The structure, morphology, and composition were analyzed by X-ray diffractometer (XRD), field emission scanning electron microscopy (FE-SEM) technique, and energy dispersive X-ray analysis (EDAX), respectively. Vibrating sample magnetometer (VSM) instrument was used for the determination of magnetic properties of each prepared sample. XRD peaks reveal nanocrystalline nature with a hexagonal single phase magnetoplumbite-like crystal structure. The FESEM micrograph shows accumulation of hexaferrite nanocompact magnetic aggregation. In addition, the size of the particles reduced with the increase in of Ce3+ ion content. The VSM analysis confirmed that SrM-HFs are hard magnetic in nature. Moreover, it is observed that the saturation magnetization and magnetic parameters of strontium ferrites decrease with the increase of the content of Ce3+ ion. In addition, Ce3+ substituted SrFe12O19 are most useful for magnetic recording and memory devices.
