Abstract:
M-type hexaferrites have attracted researchers due to their ordinary magnetic properties and utilization as media for magnetic recording and microwave devices. In this study, we have synthesized Ba 0.5 Sr 0.5 Fe 9 Ce 1 Al 2 O 19 via a conventional ceramic route. The synthesized material is treated against different temperatures and investigated structurally and magnetically by using several techniques such as x-ray diffraction, Scanning electron microscopy, and VSM respectively. Morphology of samples confirms the absence of secondary phases and uniform distribution of particles. x-ray diffraction patterns confirm the formation of the pure phase of hexaferrites. Microstructural analyses show a decrease in porosity and dislocations among sintered samples. Magnetic properties for the samples show a decrease in Ms and Mr with increasing temperature from 1225 °C to 1310 °C, while coercivity shows an increase with increasing temperature and maximum coercivity is observed at 1290 °C. The trends and occurrences can be well-linked to the structural variations and sintering effects. The results suggest that material can be used in various magnetic applications such as Recording media, and memory devices.
