“…For YFO material, a decreased coercive field was observed with an increase of magnetization values (in the case of Sr þ2 , Ni þ3 , Bi þ3 , and rare earth elements doped YFO material) as well as an increase of crystallite size. [15,16,18,19,39] Magnetization values of YFO reported in the various form such as of crystals, polycrystalline material, and nanomaterials from the literature, [11,18,34,36,[40][41][42] along with the present study, are provided in Table 2 for comparison purposes. Therefore, we suggest that the BBBO glass sintering aid is a promising candidate to improve the magnetization values of YFO materials without effecting their coercive field.…”

The addition of powdered BaO–Bi2O3–B2O3 (BBBO) glass (0.25–1.5 wt%) to yttrium orthoferrite materials (YFeO3) powder facilitates an increased crystallite size, resulting in improved magnetic properties. The required YFeO3 (YFO) materials are synthesized through the sol–gel route using tartaric acid as a chelating agent, while BBBO glass is obtained via the conventional melt‐quenching technique. The crushed glass is added to YFO powders in different wt% and compacted at room temperature, subsequently; the compacted samples are sintered at 1000 °C for 3 h. The X‐ray powder diffraction studies infer that a maximum 1.0 wt% of BBBO glass is incorporated into YFO without showing any impurity phase. The optical bandgap of each sample is calculated using the UV data with the help of the Kubelka–Munk and Tauc relation, decreasing from 2.10 to 2.04 eV with an increase of BBBO content from 0 to 1.0 wt% in YFO. The highest magnetization value (4.02 emu g−1) is observed with 1.0 wt% BBBO added in YFO surpassing pure YFO and other BBBO‐added YFO samples. In conclusion, the improved magnetization value of the 1.0 wt% BBBO added in the YFO sample can be potentially utilized in different applications.

“…The dielectric properties of YFO material obtained from the different synthetic route was studied and reported in the literature. [10,[16][17][18][19][20] The dielectric properties of materials strongly depend on the microstructure and the processing conditions during the preparation. The impedance studies were carried out to investigate the dielectric properties of different crystallite sizes of YFO materials.…”

This article reports the structural, optical, dielectric, and magnetic properties of yttrium orthoferrite (YFeO3) nanomaterials with different crystallite sizes derived from the sol–gel technique using tartaric acid as a complex agent. Different crystallite sizes (ranging from 0.4 to 2.11 μm) of YFeO3 (YFO) are fabricated by altering the sintering temperatures (in the range of 1173–1623 K) for the same duration (5 h). Rietveld refinements suggest that the different crystallite sizes of YFO exhibit a pure orthorhombic perovskite structure with the Pmna space group. It is observed that the grain size of the material increased with increasing sintering temperature. The highest magnetization value (5.078 emu g−1) is observed for the 0.89 μm size of YFO. A decrease in the optical bandgap of YFO material is observed with an increase in crystallite size. In conclusion, the optimized crystallite size is 0.89 μm for achieving the highest magnetization value of the YFO material synthesized by the sol–gel technique using tartaric acid as a chelating agent.
