Abstract: Now a days, hexa-ferrites have important attention for their novel microwave absorption applications. This innovative of this work includes the concentration of Sm3+, grain size, synthesis route, the particle size, morphology and performance of Sr3Zn2Fe24–xSmxO41 for microwave absorption application. Additionally, it describes the key elements that have a major influence on the complex permittivity, which shows the performance of microwave absorption. For 5 h, the produced samples were annealed at 1200 °C. The results of X-ray diffraction (XRD) are used to confirm that Z-type magnetic nanomaterials are single phase materials. It was observed that the size of crystallites and samarium content had the opposite relationship. A maximum cell volume of 1580 Å3 verified that iron had successfully replaced the samarium content. FTIR analysis was performed at room temperature and revealed two absorption bands with tetrahedral and octahedral vibrational sites, ranging from 400 to 600 cm−1. SEM examination can be used to study the morphological behavior of Z-type hexa-ferrites with platelet-like structure. One of the best methods for identifying substituted elemental analysis is XPS spectroscopy, which was used to confirm all constituent elements of composition (x = 0.20). At room temperature, the dielectric measurements is calculated, which included the dielectric constant, tangent loss, dielectric loss, Q-value, ac-conductivity, reflection loss, impedance analysis, and Cole–Cole plots. Additionally, for sample x = 0.20, minimum reflection loss (RL) values of − 43.6 dB and − 71.5 dB were observed at various frequency ranges (GHz), indicating that the synthesized material is appropriate for microwave absorption applications. All of the samples have the potential to be applied to high frequency, stealth technology, electromagnetic interference mitigation, radar cross-section reduction, microwave absorption-based systems, etc. [ABSTRACT FROM AUTHOR]
