Optimization of sintering temperature for realizing enhanced magnetic properties of YFeO3 ceramic derived from the sol-gel technique

Enhancement in the Magnetic Properties of Yttrium Orthoferrite Materials by the Addition of BaO–Bi2O3–B2O3 Glass Sintering Aid

“…Magnetization values and coercive field are influenced by different factors, such as particle size, synthesis condition, chelating agent, calcination temperature, and a few more factors. [ 6,18,32,34–38 ] Through Raman spectroscopy, we observed the change in the FeO bond length (red Raman shift at p8) and the increase in particle size (decrease of FWHM); these factors are primarily responsible for the improvement of magnetization value. The coercive field is also crucial for certain applications.…”

Influence of ZnSnO3 on Structural, Optical, and Magnetic Properties of YFeO3 Nanomaterials Obtained Via Sol–Gel Technique

“…The improvement of magnetization is due to the effect of crystallite size as well as the polarization in the sample (the length of the Fe-O bond affected with the increase of ZS concentration was observed through Raman analysis). [13] For comparison purposes, the magnetization values of the present study and earlier literature-reported [12,21,28,40,41] magnetization values of YFO obtained from different doping elements are provided in Table 2. This table indicates that our present values are superior to that of earlier literature-reported values.…”

“…[ 6,7 ] However, extensive research work is carried out on this material toward improving the magnetization value via changing the chelating agent, synthetic routes, doping of different rare earth elements, doping and codoping of different ions/atoms, varying temperature conditions, making the composite with other materials, etc. [ 8–30 ]…”

“…However, the sample 25.38 nm size of Y 0.8 Sr 0.2 Fe 0.8 Ni 0.2 O 3 has shown high magnetization value ( M s = 4.407 emu g −1 ) when compared to that of 25.67 nm size of YFO ( M s = 0.401 emu g −1 ), 27.65 nm size of Y 0.8 Sr 0.2 FeO 3 ( M s = 0.492 emu g −1 ), and 25.67 nm size of YFe 0.8 Ni 0.2 O 3 ( M s = 0.848 emu g −1 ) samples. Venkatrao et al [ 13 ] and Al‐Hazmi et al [ 14 ] investigated the influence of sintering temperature on magnetic properties of YFeO 3 ceramic obtained via sol–gel technique using tartaric acid as a chelating agent and via Lα‐alanine‐assisted combustion method, respectively. Venkatrao et al, observed the enhanced magnetic properties of the YFO sintered at 1050 °C ( M s = 5.12 emu g −1 ) when compared to YFO sintered at 950 °C ( M s = 4.91 emu g −1 ) and 1150 °C ( M s = 3.78 emu g −1 ).…”

Structural, Optical and Magnetic Properties of (1−x) YFeO3 + (x) Sr2Bi4Ti5O18 (where 0 ≤ x ≥ 0.005) Nanomaterials

“…However, the YFO material (58 ± 6 nm) obtained from thermal treatments of coprecipitated hydroxides have exhibited the high residual magnetization (M res ) values (273 emu mol −1 ) when compared to other methods. Venkatrao et al, 12 also observed the high magnetization (M s ) value for the YFO material obtained from tartaric acid (M s = 1.80 emu g −1 ) used as chelating agents when compared to that of YFO material obtained from other chelating agents such as citric acid (M s = 1.72 emu g −1 ), oxalic acid (M s = 0.20 emu g −1 ) and sucrose (M s = 0.40 emu g −1 ). According to Suthar et al, 13 studies, the YFO nanomaterial derived from sol-gel technique have shown improved physical properties than that of YFO nanomaterial derived from solid state reaction method.…”
