“…In the literature, there are various techniques to synthesize hexaferrite for producing microwave absorber, such as sol-gel [20,21], co-precipitation [3,22], solid state reaction [12], hydrothermal synthesis [23], citrate precursor [24], self propagating combustion [25], in situ polymerization methods [6]. The sol-gel process is an easy, inexpensive and time saving synthesis to produce 3 ferrite powders [21,26].…”

The M-type barium hexaferrite (\(\text{B}\text{a}{\text{F}\text{e}}_{12}{\text{O}}_{19}\)) nanoparticles were synthesized by polymethylmethacrylate (PMMA) assisted sol-gel process. PMMA was used as a template at \(\text{P}\text{M}\text{M}\text{A}/\text{B}\text{a}{\text{F}\text{e}}_{12}{\text{O}}_{19}\) weight ratio of 20/80, 40/60, 60/40% in the synthesis. The X-Ray Diffraction (XRD) and scanning electron microscopy (SEM) have been used to determine the structural, compositional and morphological features of particles. DC magnetic properties have been measured by using electron spin resonance (ESR) spectrometer and vibrating sample magnetometry (VSM) at room temperature. The dielectric, magnetic and microwave properties were studied by reflection/transmission technique in the coaxial waveguide at the frequency range of 2–18 GHz. The results show that the nanorod nanoparticles are ~ 200 nm in length and ~ 40–50 nm in width for the sample with \(\text{P}\text{M}\text{M}\text{A}/\text{B}\text{a}{\text{F}\text{e}}_{12}{\text{O}}_{19}\) weight ratio of 20/80. The minimum reflection loss value of rod-shaped nanoparticles achieves ~ -50 dB with bandwidth of 2.25 GHz at -20 dB.

The manufacture and study of the properties of magnetic materials requires the development of new automated devices for measuring their magnetic properties. To obtain nanosized materials with a pure phase, it is necessary to modernize former methods and develop new methods for synthesizing materials. As part of this study, a pulse magnetometer was made to study magnetic hysteresis loops. An exceptional feature of this device is the ability to conduct studies of the full cycle of the hysteresis loop using pulsed magnetic fields. M-type BaFe12O19 hexagonal ferrites were synthesized by standard ceramic, mechanochemical, and sol–gel methods. The structural, phase, and magnetic characteristics of the barium hexaferrites were studied. Methods for the synthesis of BaFe12O19 hexagonal ferrites were estimated and compared. Their structural and magnetic properties essentially depend on the method of synthesis. The mechanochemical technology makes it possible to obtain materials without impurity phases through the use of hydrated reagents in the synthesis. The use of sol–gel technology allows the synthesis to be carried out at much lower temperatures.
