“…A typical example of the obtained distributions is shown in Fig. 10, where the hyperfine-field distribution for the UA1-1 spectrum at 78 K. Finally, the procedure provided satisfactory results with respect to the spectrum of UA1-1 at 78 K. These Mössbauer parameters of the ash samples are listed in Table 4, and Mössbauer parameters of sodium [18,19], magnesium [20,21], and calcium [5,18,[22][23][24] ferrites reported previously are summarized in Table 5.…”

Mössbauer and Raman spectroscopic characterization of colored ash samples made by combustion of ancient buried Japanese cedar (Cryptomeria japonica) was carried out, and the factors governing the color tones were investigated mainly in terms of the chemical species of Fe. The ash samples displayed various unusual colors, depending clearly on the individual ancient tree and the part of it. Some of Mössbauer spectra of the ash samples showed magnetic hyperfine splittings due to internal magnetic fields. The Mössbauer and Raman spectra suggested that the primary Fe-containing species in all the ash samples was calcium ferrite, Ca2Fe2O5.

“…When the Sr 2+ concentration increases to a certain value, the environment becomes advantageous for particle growth and therefore the particle size increases. Therefore, the grain size can be refined effectively by controlling the Sr 2+ concentration in the samples [20,21]. A particle size distribution analysis software is used to obtain a histogram of the sample's particle size distribution, as shown in Fig.…”

Doping at A/B-sites can effectively improve the physical properties of perovskite ferrites. In this study, the performance of Bi0.8Ca0.2-xSrxFeO3 was investigated using the sol-gel autocombustion method. The results show that with an increase in x value, the grain size first increases and then decreases. With an increase in the doping concentration, the reunion phenomenon reduces, but the smoothness and flatness of the samples are also destroyed. Moreover, with increasing Sr 2+ concentration, particle growth is inhibited, resulting in smaller particle sizes. When the Sr 2+ concentration increases to a certain value, the environment becomes advantageous for particle growth and therefore the particle size increases. For x = 0.13, small particles are obtained. With increasing Sr 2+ concentration, the spatial modulation of the spin structure is destroyed, the lattice distorts, and the magnetic force is freed. Mössbauer spectrum measurements shows that when the Ca 2+ concentration is greater than the Sr 2+ concentration, Sr 2+ ions replace Ca 2+ ions; as a result, A-A magnetic superexchange diminishes, leading to a decrease in the hyperfine field. Appropriate doping of BiFeO3 can improve its coercivity and refine its grains and result in a larger magnetic force.
