Abstract
The present study explores the impact of varying heat treatment temperatures on the magnetic properties, structural configuration and dielectric characteristics of Sr0.67La0.33Fe11.7Zn0.1Co0.2O19 ferrite. M-type ferrite was synthesized using the traditional solid-state method, with thermal treatment temperatures incrementally increasing from 1230 °C to 1310 °C. Pure M-phase strontium ferrite was achieved at temperatures above 1250 °C. The ideal pre-sintering temperature was identified as 1270 °C, where several factors coalesced to enhance the magnetic properties, including the completion of the solid-state reaction and the diminution of the easily magnetized c-axis, which together fostered the intensification of the superexchange interaction. At this temperature, the magnetic properties reached their zenith, with a saturation magnetization (Ms) of 84.81 emu/g, a remanence (Br) of 419 mT, and a coercivity (Hcj) of 3301 Oe. Additionally, the dielectric constant was significantly high at low frequencies but rapidly declined with increasing frequency, achieving its optimal performance at 1270 °C.
