Abstract The rapid development of modern mobile communication technology puts more challenges on electronic device miniaturization and multifunction. Exploring new magneto-dielectric composite materials with excellent performance is one of the solutions for device miniaturization. In this paper, NiCuZn ferrite and Sr(Nb0.5Al0.5)0.1Ti0.9O3 dielectric materials were synthesized via the solid-state reaction method. Then they were mixed in a certain proportion. The effects of different ratios between the ferrite and dielectric phases on the magnetic and dielectric properties were investigated. The microstructure was also explored. The experimental results suggest that the ferrite content is 0.7—0.8, at which fully densified morphology and superior magnetic-dielectric performance are obtained.
