Low temperature sintering of laminated Ni0.5Ti0.5NbO4-Ni0.8Zn0.2Fe2O4 composites for high frequency applications

The laminated magneto-dielectric composites of Ni0.5Ti0.5NbO4(NTN)-Ni0.8Zn0.2Fe2O4(NZO) were prepared by the conventional solid-state sintering method. The phase composition, microstructure, dielectric and magnetic properties of the composites were investigated. The results show that the as-prepared composites are very dense and the NTN and NZO phases can coexist in the composites without any secondary phase. The as-prepared composites also exhibit excellent dielectric and magnetic properties in the frequency range from 10 MHz to 1 GHz, which make them have potential applications for high-frequency electronic devices.
