Novel magnetic-dielectric ceramics based on Li0.43Zn0.27Ti0.13Fe2.17O4 (LZTF) ferrites and Li2ZnTi3O8 (LZT) dielectrics were fabricated via a traditional solid-state reaction method. Pure spinel structure and dense morphology were obtained within a wide sintering temperature range of 1050–1150 °C. The introduction of the LZT dielectrics into the LZTF magnetic phase reduced the saturation magnetization (Ms), the saturation induction (Bs), and the coercive field (Hc). The introduction of the dielectric phase remarkably declined the FMR line width (ΔH) values from 200 Oe to 45 Oe at 9.55 GHz. Acceptable microwave dielectric properties were also obtained. The experimental results indicated that this xLZTF-(1-x)LZT (x = 10 wt.%, 35 wt.%, 60 wt.%, 90 wt.%) magnetic-dielectric ceramic system is a potential candidate for high frequency applications.

专为高频应用设计的新型尖晶石磁介电陶瓷

通过传统的固态反应方法制备了基于 Li 0.43 Zn 0.27 Ti 0.13 Fe 2.17 O 4 (LZTF) 铁氧体和 Li 2 ZnTi 3 O 8 (LZT) 电介质的新型磁电介质陶瓷。在 1050-1150°C 的宽烧结温度范围内获得纯尖晶石结构和致密的形态。将 LZT 电介质引入 LZTF 磁相中降低了饱和磁化强度 ( M s )、饱和电感 ( B s ) 和矫顽场 ( H c)。介电相的引入使 FMR 线宽 (Δ H ) 值从 200 Oe显着下降到 9.55 GHz 时的 45 Oe。还获得了可接受的微波介电性能。实验结果表明,这种x LZTF-(1- x )LZT ( x  = 10 wt.%, 35 wt.%, 60 wt.%, 90 wt.%) 磁介电陶瓷系统是高频的潜在候选者。应用程序。
