Abstract Indium-substituted strontium hexaferrites were prepared by the conventional solid-phase reaction method. Neutron diffraction patterns obtained at room temperature and analyzed using Rietveld methods. A linear dependence of unit cell parameters is found. In 3+ cations are located mainly in octahedral positions 4f VI 12 k. The average crystallite size varies within 0.84–0.65 μm. With increasing substitution, T C Curie decreases monotonically down to ~ 520 K. ZFC FC measurements showed a frustrated state. Upon maximum sizes ferrimagnetic clusters change opposite direction.

In this paper, a double E-shaped symmetric split ring resonators metamaterial inspired triple band microwave absorber (MA) for EMI shielding and stealth applications in C X is presented. The proposed comprises E shaped with two modified resonators-based copper separated by FR-4 dielectric layer thickness of 1.6 mm back annealed 0.035 an electrical dimension 0.179λ × 0.179λ, λ computed at the frequency 5.376 GHz. simulated results derived from CST Microwave Studio simulator show that there are three absorption peaks 5.376, 10.32 12.25 GHz 99.9%, 99.9% 99.7%, respectively. An equivalent circuit model used to study reflection coefficient characteristics E-field, H-field surface current distributions investigated order understand electromagnetic wave mechanism. Parametric analyses were also performed select appropriate frequencies. addition, unit cell structure shows nearly perfect absorptions over wide angle incidences up 60° both TE TM mode. MA has behavior provides effectiveness, greater than 40 dB entire measured condition, which reasonable reduction RF signal reduce impact on devices susceptible interference. simulated, experimental validation purposes showed complete mutually supportive. expected be useful applications.

In this study, SrFe12-xNdxO19, where x = 0, 0.1, 0.2, 0.3, 0.4, and 0.5, was prepared using high-energy ball milling. The samples were characterized by X-ray diffraction (XRD). Using the XRD results, a comparative analysis of crystallite sizes powders carried out different methods (models) such as Scherrer, Williamson-Hall (W-H), Halder-Wagner (H-W), size-strain plot (SSP) method. All studied prove that average nanocrystallite size increases increasing Nd concentration. H-W SSP are more accurate than Scherer or W-H methods, suggesting these suitable for analyzing spectra obtained in study. specific saturation magnetization (σs), effective anisotropy constant (Keff), field magnetocrystalline (Ha), shape (Hd) SrFe12-xNdxO19 (0 ≤ 0.5) calculated. coercivity (Hc) (about 9% at 0.4) with an degree substitution Fe3+ Nd3+, which is one main parameters manufacturing permanent magnets.
