SrCo0.2Zn0.2Fe11.6O18.8 hexaferrite was obtained by a “one-pot” green sol-gel synthesis
method 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 synthesis
process on the structure, morphology, magnetic, dielectric and ferroelectric properties of strontium
hexaferrite in view of future applications. Structural and morphological characterization using
X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron
microscopy coupled to energy dispersive X-ray spectrometry (SEM-EDX) confirmed the formation
of a Co and Zn ion incorporated M-type magnetoplumbite with c/a lattice parameter ratio of 3.919
as crystallite nanoplatelets of 32 and 53 nm in thickness and width, respectively. The magnetic
hysteresis loop of the synthesized powder recorded by a vibrating sample magnetometer (VSM) at
room temperature confirmed ...its ferromagnetic nature with a coercive field (Hc) of 2539 Oe and a
saturation 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 the
magnitude of the applied electrical field increased in the 1–24 kV/cm range. The dielectric constant
decreased with the frequency increase, in accordance with the Maxwell–Wagner model, while the
conductivity changed according to the Jonscher power law. The complex impedance was modeled
with an equivalent circuit, enabling identification of the dominant contribution of grain boundary
resistance (272.3 MW) and capacitance (7.16 pF).
