Polyaniline (PANI)/Zn ferrite composites were fabricated by simple two-step method. The crystal phase, particle size, morphology, thermal stability and conductivity were characterized. Electromagnetic parameters of PANI/Zn ferrite composites were measured at room temperature in the frequency of 2–18[Formula: see text]GHz. The prepared composite had an amorphous fluffy structure, Zn ferrite nanoparticles with diameters ranging from 20[Formula: see text]nm to 30[Formula: see text]nm are encapsulated in PANI or on PANI surface, and the thermal stability of the composite is poor. But Zn ferrite content plays a key role in influencing this structure and regulating microwave attenuation capability. The PANI/Zn ferrite composites showed an enhanced microwave absorption performance in Ku band at thin coating thickness which corresponds to RL value below [Formula: see text][Formula: see text]dB and the minimum reflection loss (RL) is [Formula: see text][Formula: see text]dB at 17.6[Formula: see text]GHz with the coating thickness of 1.4[Formula: see text]mm.

“…Until recently, the ceramic method was the most widely used [6,7]. Spinels are also obtained by the method of aerosol pyrolysis [8,9]. In this case, salts of transition metals are deposited on a substrate heated to 350-500 о С; when decomposed, they are annealed at the temperature of about 900 о С.…”

Comparative assessment of phase formation in the system ZnO-CeO2-Fe2O3-Cr2O3, obtained using a number of technological methods, is carried out. Spinel phase formation is established for all materials studied, except ZnO-CeO2. Synthesized materials are examined with X-ray phase analysis, low-temperature nitrogen adsorption, and scanning electron microscopy. It is shown that the synthesis in the presence of an organic precursor allows obtaining fine spinel samples. High catalytic activity of the synthesized materials, containing the spinel phase, is established in the process of methyl orange oxidative destruction in the presence of hydrogen peroxide. It is proved that with an increase in the number of chromium cations in the sample, the catalytic activity of the materials also increases. Zinc ferrite, despite the considerably more developed surface, and ZnO /CeO2 are not very effective in this process. The data obtained is useful for the development of materials for wastewater treatment at industrial enterprises, which use organic dyes in their production cycles.

“…The ferromagnetic (Fe 3 O 4 ) particle has spontaneous magnetization with the A-site moments aligned antiparallel to the B-sites at the temperature below the Curie point (860 K). 12,13) The saturation magnetization is an intrinsic property of ferromagnetic and one of the factors that influences the nature of ferromagnetic materials, which is independent of temperature, particle size, and morphology. At the same time, the preparation process also influences the size and morphology of the nanoparticles.…”

A one-step hydrothermal method in different dc magnetic fields was used to prepare the Fe3O4 nanoparticles. Under the magnetic field, the average particle size decreased from 72.9 to 41.6 nm, meanwhile, the particle crystallinity is greatly improved. The magnetic field enhances its saturation magnetization and coercivity. The high magnetic field induce another magnetic structure. At room temperature, these nanoparticles exhibit superparamagnetism whose critical size (Dsp) is about 26 nm. The Verwey transition is observed in the vicinity of 120 K of Fe3O4 nanoparticles. The effective magnetic anisotropy decreases with the increase of the test temperature because of the Hc decreased.
