“…The obtained values are similar to that obtained in literature [45] and shows an increasing trend with the increase of doping concentration because Sm 3+ (150.4 g/mol) has greater molar mass than Fe 3+ (55.845 g/mol). This increase is consistent with literature reports for doping La 3+ ions in Ni-Zn-Cd ferrites [48] and Nd 3+ ions in Mg-Cd ferrites [25]. This increase in exp r leads to a decrease in the porosity of the samples and vice versa.…”

“…At the optimum temperature, the gas molecular diffusion and the occurring chemical reaction rates are in equilibrium. On the contrary, at lower and higher temperatures, the gas response is limited by the rate of chemical reaction and the gas diffusion, respectively, slowing down the reaction rate [25,32].…”

Cadmium zinc ferrites Cd0.5Zn0.5SmxFe2-xO4 nanoparticles were synthesized with different concentrations x = 0.00, 0.01, 0.02, 0.04, 0.06, and 0.08, via the wet chemical co-precipitation method. The effects of the Sm3+ doping on the structural, morphological, compositional, and magnetic properties have been investigated. The structural analysis is performed using X-ray diffraction (XRD) with Rietveld refinement. The results indicate great crystallinity in the FCC Fd3m spinel structure of Cd0.5Zn0.5SmxFe2-xO4 nanoparticles. The crystallite size was estimated using Debye-Scherrer, Williamson–Hall, Size-strain plot (SSP), and Halder-Wagner (H-W) methods. It revealed a decreasing trend with the increase of Sm-doping concentrations until the solubility limit at around x = 0.04. The spherical morphology of the samples was investigated using transmission electron microscopy (TEM) with minor agglomeration as a benefit of using the capping agent polyvinylpyrrolidone (PVP). Raman spectroscopy validates the incorporation of trivalent Sm3+ in the octahedral sites. X-ray photoelectron spectroscopy (XPS) verified the elemental compositions as well as the purity of the samples and the incorporation of the dopants. A vibrating sample magnetometer (VSM) was used to study the magnetic properties, and which indicates the superparamagnetic behavior of the prepared samples. The prepared samples were tested as liquefied petroleum gas (LPG) sensors by studying their sensitivity, optimum working temperature, response time, and recovery time. The doping of samarium ions reveals a great increase in LPG sensing sensitivity and optimum temperature with decreasing response and recovery times.

“…In conclusion, this article will provide a comprehensive overview of the effect of synthesis methods and a comparative study of the structural properties of micro and nano ferrites. By understanding the relationship between synthesis methods and structural properties, it is possible to optimize the synthesis process and tailor the properties of ferrites for specific applications [14,15]. Mn(x)Zn(1-.x)Fe204 Co-precipitation and ceramic methods have been used to synthesis ferrites [10,16,17].…”

In this study, Mn(x)Zn(1-x)Fe2O4 ferrite samples with x=0.4 and 0.6 were synthesized using a solid-state method and co-precipitation method. In order to determine the effects of various concentrations (x) on the ferrite's structure, particle size, and crystalline phases, prepared samples were analysed using X-ray diffraction (XRD). The XRD patterns revealed that the synthesized samples display a single-phase cubic spinel structure.FTIR analysis showed for both synthesis method have absorption band in the range 400 to 1000 cm-1.SEM analysis shows extreme homogeneity of all the samples. EDX analysis was used to examine for Mn0.4Zn0.6Fe204,The prepared ferrites powders contain Mn, Zn, and Fe, as shown in both synthesis methods.In this approach, alternative synthesis routes for these ferrites are suggested in this study in order to get around some limitations of the traditional preparation method.
