Abstract
BixY3–xFe5O12 (x = 0.0, 0.9, 1, 1.1, 1.2, and 1.3) were synthesized by the sol–gel method to investigate the effect of Bi substitution on the structural and magnetic properties of YIG. The XRD results indicate that all the diffraction peaks belong to the pure phase. The Mössbauer analysis shows an increase in the ratio and also a line broadening at tetrahedral sites, which suggests a relocation of yttrium ions at dodecahedral sites with iron ions at octahedral sites. The saturation magnetization fluctuates with increasing bismuth content, which has been explained based on Mössbauer results. The change in vibrational band broadening and the observation of a new band in the far‐FTIR spectra confirm the proposed cation relocation.
