In this article, REFe0.5Cr0.5O3 (RE = La, Y) is prepared by sol–gel method, and the structure is characterized and analyzed by X‐ray diffraction, scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, Mössbauer spectroscopy, and magnetism. A reference for future studies of the effect of clusters on Cr‐doped iron‐based calcium is provided. The synthesis of REFe0.5Cr0.5O3 (RE = La, Y) using the sol–gel method is focused and their structural differences are investigated. The results of X‐ray diffraction show that the chan...
