Sol-gel assisted synthesis and tuning of structural, photoluminescence, magnetic and multiferroic properties by annealing temperature in nanostructured zinc ferrite

Role of Different Fuels and Sintering Temperatures in the Structural, Optical, Magnetic, and Photocatalytic Properties of Chromium-Containing Nickel Ferrite: Kinetic Study of Photocatalytic Degradation of Rhodamine B Dye

“…Therefore, the saturation magnetization values of all the samples were determined from the plot of M and 1/ H in the high-field region. The obtained saturation magnetization for NCFGs shows a regular but decreasing trend with increasing sintering temperature, which is in contrast to recent studies of magnetic properties of ferrites, in which an increase in M s with increasing sintering temperature was noticed. , However, both NCFPs and NCFUs showed a similar but irregular trend with respect to sintering temperature as displayed in Figure d. In addition, at a particular sintering temperature, the effect of different fuels on the magnetic saturation of Ni-Cr ferrites can be seen, but no regular trend has been observed (Figure d).…”

In addition, at a particular sintering temperature, the effect of different fuels on the magnetic saturation of Ni-Cr ferrites can be seen, but no regular trend has been observed ( Figure 9 d). The observed results for saturation magnetization, in general, can be explained on the basis of particle size and distribution of cations between A and B sites due to thermal treatment.…”

Optimization of the structural, optical, and magnetic properties of sol-gel derived La3+ substituted nanostructured barium hexaferrites

“…All structural parameters of samples BL 0 to BL 5 were depicted in table 1. Using Full Prof software [33], the Rietveld refinement was carried out to get the refined structural parameters for comparison with experimentally determined values. The peak profile is described by the pseudo-Voigt function, and the background was fitted with a polynomial of six coefficients.…”

Exploring moisture adsorption on cobalt-doped ZnFe2O4 for applications in atmospheric water harvesting

“…The obtained ZnFe 2 O 4 powder was washed using ethanol to remove excess surfactant. 25 Then, the washed ZnFe 2 O 4 powder was calcined at 800 °C for 8 h. 23 To prepare 60% cobalt-doped ZnFe 2 O 4 samples, a 0.3 M (2.63 g/30 mL) EDTA solution in 30 mL of ammonia was prepared and kept on a hot plate. Next, a 0.06 M (1.74 g/100 mL) solution of cobalt nitrate hexahydrate, 0.04 M (1.19 g/100 mL) solution of zinc nitrate hexahydrate, 0.2 M (8.08 g/100 mL) solution of iron nitrate nonahydrate were mixed dropwise in an EDTA solution.…”
