Magnetic properties and magnetoresistance effect of SnFe2O4 spinel nanoparticles: Experimental, ab initio and Monte Carlo simulation

Magnetoresistance (MR) properties of magnetic materials

“…21 In its development, several material structures that exhibit good MR values have been discovered, including perovskite materials, [7][8][9]22,25 alloy, 13,17,23 Kagome magnets, 10,[13][14][15][16]24 and spinel. 11,12,26,27,29 In the past few decades, perovskite materials in manganese oxide compounds with mixed valence states have become one of the most intriguing research topics in the study of magnetic materials. This is because of their highly varied multifunctional properties in terms of magnetism, making them suitable for diverse applications such as magnetic refrigeration, spintronics, and solid oxide fuel cells (SOFC).…”

“…The XRD characterization results for several spinel materials indicated that these substances had a single phase with a cubic spinel structure within the Fm 3m space group. For example, in the case of SnFe 2 O 4 , this cubic spinel structure can be clearly identied through X-ray diffraction (XRD) analysis, 11 MCr 2 S 4 (M = Fe & Co), 121 and Fe 3 O 4.…”

“…When hysteresis loops are not form, it indicates coercivity below the blocking temperature (TB). The coercivity (H c ) increases with decreasing temperature and reaches a value of approximately H c is in the range of 555.61 Oe at T = 5 K. 11 There are differences in the magnetization values that can be explained by size scaling, 124 In the Monte Carlo simulation method, the morphology of nanoparticles is considered perfect with a cubic shape, whereas in experiments, crystal defects are present in samples and may not be controlled. The resistivity-temperature (r-T) curve of spinel material (SnFe 2 O 4 ) indicates semiconductor behavior with a decrease in resistivity as the temperature increases.…”

Synthesis, characterization, and electrochemical evaluation of SnFe2O4@MWCNTS nanocomposite as a potential hydrogen storage material

“…Tin ferrite nanoparticles (SnFe 2 O 4 ) have received a considerable amount of attention due to their wide applications in various fields, and belong to a broad group of magnetic nanoparticles (MNPs) with inverse spinel structure [ 15 ]. The properties of spinel ferrites are strongly correlated with the distribution of cations between tetrahedral and octahedral sites [ 16 , 17 ]. In the inverse spinel of SnFe 2 O 4 , Sn 2+ ions occupy octahedral sites, while Fe 3+ ions are evenly distributed between tetrahedral and octahedral sites [ 18 ].…”
