AB  - SrCo0.2Zn0.2Fe11.6O18.8 hexaferrite was obtained by a “one-pot” green sol-gel synthesismethod utilizing aqueous mandarin orange (Citrus reticulata) peel extract as an eco-friendly reactant.The research objective was to analyze the influence of cobalt and zinc co-doping and the synthesisprocess on the structure, morphology, magnetic, dielectric and ferroelectric properties of strontiumhexaferrite in view of future applications. Structural and morphological characterization usingX-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electronmicroscopy coupled to energy dispersive X-ray spectrometry (SEM-EDX) confirmed the formationof a Co and Zn ion incorporated M-type magnetoplumbite with c/a lattice parameter ratio of 3.919as crystallite nanoplatelets of 32 and 53 nm in thickness and width, respectively. The magnetichysteresis loop of the synthesized powder recorded by a vibrating sample magnetometer (VSM) atroom temperature confirmed its ferromagnetic nature with a coercive field (Hc) of 2539 Oe and asaturation magnetization (Ms) and remanent magnetization (Mr) of 44.6 emu/g and 21.4 emu/g,respectively. Room temperature ferroelectric loops measured at 100 Hz showed a maximal (Pmax)and a remanent (Pr) polarization of 195.4 and 31.0 nC/cm2, respectively. Both increased when themagnitude of the applied electrical field increased in the 1–24 kV/cm range. The dielectric constantdecreased with the frequency increase, in accordance with the Maxwell–Wagner model, while theconductivity changed according to the Jonscher power law. The complex impedance was modeledwith an equivalent circuit, enabling identification of the dominant contribution of grain boundaryresistance (272.3 MW) and capacitance (7.16 pF).
