“…The general chemical composition for M-type hexaferrite is AFe 12 O 19 , where A can be Sr, Ba, Pb, etc There is a requirement of two formula units to form a sole hexaferrite containing 64 atoms. 3 The crystal structure of the hexaferrite consists of oxygen anions arranged in "S" and "R" blocks. The "S" block follows a closed pack cubic structure, while the "R" block follows a closely pack hexagonal structure.…”

The present report comprehensively investigates the influence of sol-gel synthesized cobalt and zinc-substituted SrFe12O19 on the morphological, structural, dielectric, and electrical characteristics. XRD analysis revealed that the substituents successfully replaced Fe3+ ions, leading to the existence of a single-phase magneto-plumbite structure of M-type hexaferrite. The crystallite size decreases from 48.94 nm to 45.9 nm as the level of substitution increases in SrM hexaferrite. With increasing the substitution level, SEM micrographs exhibited the formation of grain clusters. The electrical parameters had been investigated in the 20 Hz to 2 MHz frequency range. In the low-frequency region, both dielectric constant and loss tangent decreased with Co-Zn substitution. Sr〖Co〗_0.8 〖Zn〗_0.8 〖Fe〗_10.4 O_19 sample shows the minimum value of AC conductivity 3.95×10-5 Ω-1m-1 in the high-frequency region. Both the electric modulus and impedance spectra exhibit non-Debye behavior in all samples. The Cole-Cole plots (M'' versus M') reveal the existence of a single semicircular arc in the x = 0.0 sample, caused by the grain boundary contribution.
