“…The current observations in the magnetic material system may indicate exciting outcomes. The formation of M-type hexagonal ferrites is also verified as the c/a ratio ranges between 3.9360-3.9720 as shown in table 1 which is less than 3.98 as reported previously [36][37][38][39]. Furthermore, the change in lattice parameters happened due to the difference of sintering temperature.…”

The sintering temperature is a key way to tune the structural and magnetic properties of M-type hexaferrites. Here the effect of sintering temperature on BaFe9.95Al2Mg0.05O19 M-type hexagonal Ba-hexaferrites was studied. X-ray diffraction analysis revealed the presence of Fe2O3 impurity phases in all samples. The results showed that as the sintering temperature increased, the saturation magnetization and remanence ratio initially increased, then decreased at higher temperatures. On the other hand, the coercivity and magnetocrystalline anisotropy field decreased first, then increased. The morphology suggested that average grain size consistently grew between 800-2800 nm with increasing temperature. The optimal magnetic properties of BaFe9.95Al2Mg0.05O19 were achieved at a sintering temperature of 1280 ℃, with saturation magnetization 49.94 emu/g, coercivity 4.99 kOe, anisotropic field 1.5kOe, and magnetic moment of 9.4097µB. The findings suggest that the magnetic properties of M-type hexagonal ferrites can be significantly enhanced by optimizing the sintering temperature, which has implications for the development of high-performance self-biased circulators, Magnetic filters, and other magnetic applications.

Due to it has large saturation magnetization (Ms), high magnetocrystalline anisotropy field and high ferromagnetic resonance (FMR) frequency. Barium ferrite (BaM) has attracted more and more attentions in the fields of magnetic recording media, permanent magnets and microwave devices. Here, BaM thin films were deposited on Pt-coated Si substrate, and the effect of annealing temperature on the microstructure and magnetic and microwave properties of barium ferrite thin films in detail. It is found that when the BaM thin film was annealed at 1035°C, it has good properties. The XRD data provide clear evidence that the BaM thin films have high c-axis orientation, and the Lotgering factor is as high as 0.96. The AFM morphology show that BaM grains are out of the film plane, and there are hexagonal. The magnetic hysteresis curves indicated that Both saturated magnetization (4πMs), remanence ratio and OP coercive (Hc) increase with increasing Ta, and get the maximum value at 1035 °C. The ferromagnetic resonance (FMR) measurement show that the FMR linewidth is 143 Oe@50 GHz, it means that this this sample has low microwave loss in millimeter wave loss. These results make sure that this BaM thin film is possible use in millimeter wave devices such as filers, circulators and isolators.
