Abstract:
Polycrystalline spinel ferrites with a composition of Li$_{0.33}$Fe$_{2.29}$Zn$_{0.21}$Mn$_{0.17}$O$_{4}$ have been synthesized using the ceramic technology at sintering temperatures of 950, 1000, 1050, and 1100$^\circ$C. The magnetic hysteresis loops and permeability of the objects of study are analyzed in magnetic fields from -400 to +400 A/m. The behaviors of the complex permittivity and complex permeability and the reflectance on a metal plate are investigated in the frequency range of 0.01 – 7.0 GHz. It is established that the optimal range of sintering temperatures for the synthesized ferrites is from 1050 to 1100$^\circ$C. It is shown that the Li$_{0.33}$Fe$_{2.29}$Zn$_{0.21}$Mn$_{0.17}$O$_{4}$ spinel ferrite intensely absorbs electromagnetic radiation in the frequency range of 0.05 – 7.0 GHz. Possibilities of practical application of the results obtained are discussed.
