“…Therefore, the A-B interaction was decreased and the B-B interaction was increased. Furthermore, Y-K angles can be determined using = − − (Table 7) [19]. The spin canting angles of the as-prepared series of samples increased with La 3+ concentration suggest that the increased favor for triangular spin arrangement on octahedral (B-) sublattice and A-B interaction decreased.…”

“…The literature indicates that there are numerous conventional and nonconventional routes of preparation, including the solid-state method [14], sol-gel self-igniting route [15,16], a hydrothermal technique [17], the microemulsion route [18], and the co-precipitation technique [19], which have been successfully used to control the properties of spinel ferrites. The main drawbacks of traditional methods are low reproductivity, the use of high temperature, and contamination problems.…”

Metal-Organic-Frameworks: Low Temperature Gas Sensing and Air Quality Monitoring

“…In magnetic gas sensors, the magnetic properties of the sensing material are changed upon exposure to the target gas molecules; the change can be measured by, for example, application of the Hall effect, magnetization, spin orientation, ferromagnetic resonance, the magneto-optical Kerr effect, or the magnetostatic wave oscillation effect [8,[13][14][15][17][18][19][20][21][22][23][24][25][26]31,34,35]. Sensing materials for gas detection can be classified into metal oxides [16,36,37], conductive and non-conductive polymers [38][39][40][41], carbon-based materials (e.g., graphene, carbon nanotubes, etc.)…”

Supremacy of Magnetic Behaviour in n-Heptane Based M Doped Barium Ferrite (BaFe2O4) Nanoparticles (M: Co, Ni and Mn)

“…The application of spinel ferrite is originated from particular properties like structural, magnetic and dielectric properties. The permeant magnetization of ferrite turns the attention of researchers towards the best utilization like supercapacitor, photocatalysis and sensor [1][2][3]. The spinel structure closely connected to magnetic properties and its general structure is AB 2 O 4 form, where A is represented as divalent and B as trivalent cations.…”
