摘要：
Z-type Ba3Co2Fe24O41 (Co2Z) ferrite with different additives (Bi2O3, SiO2, Al2O3, and MgO) was prepared by solid-state synthesis method. Effect of sintering additives on structural, magnetic, and dielectric properties has been investigated. All XRD patterns confirmed the single-phase Z-type ferrite; however, a minor trace of M-type ferrite was observed with SiO2 additive. FTIR studies verified that the additive ions do not occupy any crystallographic sites of Co2Z ferrite. SEM micrographs revealed that SiO2, Al2O3, and Bi2O3 promote hexagonal platelet-shaped structure of different size. Magnetic measurements showed that coercivity increased and saturation magnetization decreased with sintering additives. All the sintering additives effectively reduced complex permittivity and dielectric losses of Co2Z ferrite.
