Effect of BBSZ-LMZBS Co-doped NiCuZn Ferrite on Gyromagnetic, Soft and Static Magnetic Properties

다국어 초록 (Multilingual Abstract)

In this study, BBSZ-LMZBS co-doped Ni0.22Cu0.31Zn0.47Fe2O4-based ferrites were prepared by low temperature (880 °C) solid state reaction. The microstructure, static magnetic, soft magnetic and gyromagnetic properties ofNiCuZn ferrites with different doping amounts were studied. XRD and SEM showed that the samples were successfully synthesized, and BBSZ-LMZBS promoted the low-temperature sintering of the samples through the liquid phase sintering mechanism. With the increase of the doping amount of BBSZ-LMZBS, the static magnetic property Ms of the sample reaches a maximum value of 94.42 emu/g (x=0.35), and Hc reaches a minimum value of 81.84 Oe (x=0.40). From x=0.05 to 0.40, the soft magnetic property μ′ value of the sample decreases by 40% (from 30.6 to 9.3), the ε′ value decreases from 21.8 to about 13, and the tanδ value remains small and stable. The gyromagnetic property value of the sample at 9.55GHz decreases from 872 Oe to 230 Oe, a decrease of 24%.
