Structural analysis through cations distributions of diamagnetic Al3+ ions substituted Ni-Zn-Co ferrites

Correlation among the structural, electric and magnetic properties of Al3+ substituted Ni–Zn–Co ferrites

“…The samples' noisy XRD data and the strongest reflections' intensities to the background ratios were very low, and slightly high values of profile factor ( R p ) were obtained. 1 The chi2 values range from 1.02 to 1.19, 1 indicating refinements are reliable in the goodness of fitting approach towards the samples' specific structures. The crystal structure of the composition x = 0 drew through the Rietveld refinement XRD parameters CIF file and is shown in Fig.…”

“…08-0234. 1 Rietveld refinement of the X-ray diffraction data using FULLPROF suite program 26 brought from the Jahan et al 2021(1). Refinement of the XRD data also confirmed the formation of Ni 0.4 Zn 0.35 Co 0.25 Fe (2− x ) Al x O 4 (0 ≤ x ≤ 0.12) spinel ferrite system with the space group Fd 3̄ m (227) (27 22).…”

“…Recently, ferrimagnetic oxides, or ferrites, have risen to significance due to their intelligent designs of chemical compositions and crystal structures with suitable characteristics. 1 Spinel-based cubic ferrite possesses dual electric and magnetic properties depending on its structural compositions, cationic arrangements, sintering temperature, and fabrication methodology. 1–4 Several synthesis techniques, including solid-state reactions, sol–gel, hydrothermal, ball milling, co-precipitation, etc.…”

“…Ni 0.4 Zn 0.35 Co 0.25 Fe (2− x ) Al x O 4 (0 ≤ x ≤ 0.12) was a newly studied composition. 1 However, these studied compositions' optical, electrical, and magnetic properties remain unexplored. Thus, the newly made ferrites studies appear intriguing to see how doping changes properties that make them appropriate to high-frequency devices.…”

Functionalized hybrid magnetic catalytic systems on micro- and nanoscale utilized in organic synthesis and degradation of dyes

“…Cationic exchange is an applicable method to produce various structures for specic applications. 230,238 6. Reusability of micro and nanoscale magnetic catalytic systems One of the most signicant parameters of catalytic systems is their reusability, which affects their commercial applicability, suitability, and sustainability.…”
