Abstract
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.
