Abstract

<jats:title>Abstract</jats:title><jats:p>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<jats:sub>0.5</jats:sub>Sr<jats:sub>0.5</jats:sub>Fe<jats:sub>9</jats:sub>Ce<jats:sub>1</jats:sub>Al<jats:sub>2</jats:sub>O<jats:sub>19</jats:sub> 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.</jats:p>
