“…The saturation magnetization (Ms), remanent magnetization (Mr), and coercivity (Hc) were 0.5 emu/g, 0.2 emu/g, and 4471.0 Oe, respectively (Figure 4.). Numerous studies have investigated the magnetic parameters of M-type BaFe12O19 nanoparticles, exhibiting Ms = 41, 54.97, 75.54 emu/g, Hc = 5450, 4964.5, and 2800 Oe [9][10][11][12], which show more paramagnetic properties in comparison to synthesized BaFe2O4 nanoparticles.…”

In the last decade, spinel structures have been widely explored due to widespread applications in antibacterial nanocomposites, memory devices, catalysts, photocatalysts, high-frequency devices, and electromagnetic absorbing materials. In this study, BaFe2O4 spinel structures were synthesized through the sol–gel method using a low sintering temperature and were identified by vibrating sample magnetometer (VSM), X-ray powder diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, field emission scanning electron microscopy (FE-SEM), and vector network analyzer (VNA) analysis. Results showed that uniform and pure crystal structures of BaFe2O4 nanoparticles were prepared based on the sol–gel method. Finally, BaFe2O4 nanoparticles were blended by silicone rubber to characterize the microwave absorption properties of the nanocomposite at the ku-band frequency. According to the VNA results, the BaFe2O4/silicone rubber nanocomposite with 1.75 mm thickness absorbed more than 94.38% of microwave irradiation along the ku-band frequency and the maximum reflection loss of the BaFe2O4/silicone rubber nanocomposite was 51.67 dB at 16.1 GHz.

“…The barium hexaferrite material is a ferrite-based magnetic material that has large magnetic loss properties and dielectric loss properties (Handoko et al, 2020), high magnetization saturation, high conductivity, and high-temperature curie (Kumar et al, 2020). These characteristics make barium hexaferrite a better absorbent material for electromagnetic radiation than other materials (Bahadur et al, 2017). So far barium hexaferrite has only been developed through the formation of compounds and the addition of composite elements such as TiO 2 , Al 2 O 3 dan CuCO 2 SO 4 (Peymanfar et al, 2020;Vinnik et al, 2018;Yang et al, 2019).…”

Betel leaf is a typical Indonesian herbal plant that propagates on other tree trunks. So far, betel leaf has only been used in biomedicine and traditional medicine, whereas the chemical compounds of betel leaf can be used to absorb electromagnetic waves. In this mini-review, we review several research results to discuss the potential effectiveness of betel leaf in barium hexaferrite as an absorber of electromagnetic radiation. We compiled this mini-review based on the literature review method that is discussed extensively and in-depth regarding the chemical composition of betel leaf, modification of the development of barium hexaferrite material with betel leaf media extract, characteristics of BaFe12O19 as absorption of electromagnetic waves, and the effectiveness of media extracts in BaFe12O19 as absorption of electromagnetic waves. Based on the results of the literature review, the modification of BaFe12O19 material synthesis can include microemulsion, solid-state, coprecipitation, sol-gel, and hydrothermal synthesis. So far, hydrothermal synthesis is a synthesis method of mixing betel leaf extract media and ferrite-based magnets that have been studied before. Betel leaf in ferrite-based magnetic materials has been studied not to damage the surface morphology and characteristics of the magnetic material. The results of the assessment also show the effectiveness of adding other elements or compounds such as Ni, Al2O3, and composites in ferrite-based magnetic materials that can absorb more than 90% of electromagnetic waves in the frequency range 2-18 GHz.

“…Barium hexagonal ferrite has become an interesting object of research thus far after being able to be used for semi-hard magnet applications in electronic components, magnetic memory, recording media, and in particular as a microwave-absorbing material (MAM) [1][2][3][4]. Several electrical components that work at high frequencies experience interference due to these adverse microwaves caused by electric and magnetic fields [5][6][7][8].…”

Ba1-xLaxFe12O19 with ion substitution La3+ (x = 0 – 0.7) has been produced via the mechanical milling technique of the solid reaction method. Considering that Ba1-xLaxFe12O19 is expected to be used as a microwave absorbent, it is necessary to characterize its structural and magnetic features. The refinement results of the X-ray diffraction (XRD) data show that a single-phase hexagonal structure (space group P63/mmc) is obtained for x = 0 and x = 1, while for the composition of x 0.1 is multiphase. The lattice parameters and crystal volume decreased, whereas the lattice strain was found to advance with increasing La substitution in the sample. For x = 0.1, the crystallite size is constant while the lattice strain increases. Employing a scanning electron microscope (SEM), the observation of particle morphology shows that the single-phase (x = 0 and x = 0.1) has a comparably unvarying particle size circulation, while for x 0.1, different particle shapes and sizes are found. The saturation magnetization raises while the coercivity field reduces due to the substitution of La for x = 0.1. Furthermore, for x 0.1, the saturation magnetization decreases while the coercivity field increases.
