“…The work of the other group reporting shows that the lattice distortion induced by co-doping Fe-SnO 2 enhance ferromagnetic saturation magnetization of the compared with not co-doped one [26]. As shown in Figure 7 oxygen vacancies has a great impact on the FM property of Fe doped SnO 2 [50]. The ferromagnetic behavior of Fe-doped SnO 2 thin films is caused by the coupling of ferric ions through an electron trapped in an oxygen vacancy [60].…”

Due to their potential application in the field of spintronics, the discovery of various types of oxide-based dilute magnetic semiconductors (ODMS) materials that might work at practical room temperature ferromagnetism (RTFM) has recently attracted great attention. Among ODMS materials, transition metal ™ doped tin oxide (SnO 2) compounds are important for the investigation of ferromagnetism due to its special important property such as high chemical stability, high carrier density, n-type behavior and trait long range ferromagnetism. However, the question of understanding the mechanism of ferromagnetism (FM) process is still not fully understood in these materials, due to unable to know exactly whether its FM property arises from the nature of the intrinsic property or secondary phases of the material. According to the results from many literature surveys, the mechanism of magnetic ordering responsible for magnetic exchange interaction in these materials is highly affected by oxygen vacancy, defects, dopant types and concentration, temperature, sample preparation method and so on. In this chapter, we reviewed the mechanism of ferromagnetism observed of Ni, Mn and Fe-doped SnO 2 materials.

“…The SnO 2 Fe and SnO 2 Fe/Pt samples show a pair of peak maxima at 1.27, 2.6 and 1.35, 2.7 Å, respectively. In the case of SnO 2 Fe, the peaks significantly shift from the standard Fe 3 O 4 (1.40 and 2.8 Å), 75 which may be due to its lattice intercalation in SnO 2 , whereas the peak from SnO 2 Fe/Pt shows a minor shift from the standard Fe 3 O 4 ; hence, there may be an additional island of Fe 3 O 4 on the SnO 2 surface. This signal was not evident in the XRD analysis.…”

Handheld Crop Pest Sensor Using Binary Catalyst-Loaded Nano-SnO₂ Particles for Oxidative Signal Amplification

In agriculture, pest management is a major challenge. Crop releases volatiles in response to the pest; hence, sensing these volatile signals at a very early stage will ease pest management. Here, binary catalyst-loaded SnO 2 nanoparticles of <5 nm were synthesized for the repeated capture and oxidation of the signature volatile and its products to amplify the chemoresistive signal to detect concentrations as low as ≈120 ppb. The sensitivity may be due to the presence of the elements in the Sn−Fe−Pt bond evidenced by extended X-ray absorption fine-structure spectroscopy (EXAFS) that captures and oxidize the volatile without escaping. This strong catalyst may oxidize nontarget volatiles and can cause false signals; hence, a molecular sieve filter has been coupled to ensure high selectivity for the detection of Tuta absolutainfestation in tomato. Finally, with the support of a mobile power bank, the optimized sensor has been assembled into a lightweight handheld device.

“…In contrast, nanocrystalline Sn 0.8 Fe 0.2 O 2 films had a Fe 2 O 3 impurity phase that displayed excitonic features due to 2p-3d hybridization. 49 The changes in electronic structure and magnetism of Fe-SnO 2 thin films grown by radio frequency magnetron sputtering 50,51 were attributed to bound magnetic polarons. Sn 1Àx Fe x O 2 thin films deposited by the spray pyrolysis method 52 exhibited secondary phases like b-Fe 2 O 3 and b-Fe 3 Sn as x changes from 0.078 to 0.396.…”
