Abstract
The study presents a ferroelectric–ferromagnetic composite based on a doped PZT‐type and ferrite powders. Ferroelectric powder (in amount of 90 wt‐%) was based on multicomponent PZT‐type materials, while nickel–zinc ferrite Ni1–xZnxFe2O4 (in amount of 10 wt‐%) served as the magnetic component of the composite. The syntheses of the ferroelectric–ferromagnetic composite's components were performed using solid‐phase sintering, while final densification of the synthesized powder was achieved using free sintering. X‐ray analysis of the composite confirmed the presence of strong maxima originating from particular PZT‐type material phases, as well as weak peaks from the Ni0.64Zn0.36Fe2O4 ferrite, without foreign phases. The microstructure of the fracture of the ferroelectric–ferromagnetic composites shows that the ferrite grains on the surface of the ferroelectric component are distributed heterogeneously. Magnetic studies have characterized composite as a soft ferromagnetic material. The study indicated the influence of the magnetic subsystem on the electrical properties. In the two‐phase PBZTMC–NZF ceramic composite, the magnetic component causes the decrease in electric permittivity and increased value of the dielectric losses.
