Cs+ substituted SrZnFe2O4 nanoparticles: Analysis of structural, morphological and electrical behavior

Suriani Abu Bakar

Abstract

The effect of Cs+ substitution on strontium zinc ferrites was reported. The cubic spinel phase of Sr0.5Zn0.5Fe2-xCsxO4 (0.01 ≤ x ≤ 0.09) was revealed from XRD analysis. The variation of lattice parameters with Cs+ substitution is attributed to Vegards law. The particle size of X-ray diffraction and W‒H were calculated in the range of 21–32 and 41–56 nm, respectively. Williams Hall and the size–strain plot are frequently utilized to understand the mechanical and structural properties of spinel ferrites. The morphological structure of strontium zinc spinel ferrites was examined by SEM. SEM depicts nanorods and spherical-like structures with a porous nature. FTIR was used to observe the bands of spinel ferrites within the range of 400–4000 cm−1. The absorption bands were obtained from 400 to 600 cm−1 range and these bands are used in fingerprint regions. Ohmic nature was revealed through I–V characteristics of Cs+-doped strontium zinc ferrites. Electrical properties enhanced significantly with varying molar contents of cesium. Elemental analysis and band region of cesium-doped Sr–Zn spinel ferrites were also reported. It was observed that Cs+ modifications may enhance crystallinity as well as structural and morphological stabilities of strontium zinc ferrites. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.
