This in-depth investigation delves into the consequences of simultaneously substituting Samarium (Sm) and Cadmium (Cd) in Co2X hexagonal ferrites, particularly in the presence of a hematite phase. Employing precise synthesis and characterization techniques such as X-ray diffraction and scanning electron microscopy, we explore the intricate details of the ferrite's structure, grain size, and morphology. Magnetic properties, encompassing saturation magnetization, coercivity, and magnetic anisotropy, are closely examined, unveiling the nuanced impact of Sm and Cd co-substitutions. Mössbauer spectroscopy provides valuable insights into hyperfine interactions and the local environments of iron atoms.

Furthermore, impedance spectroscopy and dielectric spectroscopy analyses reveal changes in electrical conductivity, permittivity, and dielectric loss tangent across varying frequencies due to the co-substitutions. The coexistence of a hematite phase is meticulously examined, with advanced characterization techniques shedding light on interfacial interactions and phase compositions. These outcomes significantly contribute to an enriched understanding of hexagonal ferrite materials, presenting possibilities to customize their properties for applications such as magnetic storage and microwave devices. In essence, this research not only advances fundamental knowledge in material science but also opens avenues for engineering ferrite materials with tailored functionalities.
