摘要: A thorough study of the Mossbauer spectra (MS) a lightly iron doped (2%) polycrystalline La0.75Ca0.25MnO3 compound has been carried out from T=4.2 K up to 300 K. The MS for T>Tc and at show one component. corresponding hyperfine parameters are compatible with S=5/2 Fe3+ in octahedral coordination. As temperature increases 4.2 consist several broad sextets doublets (especially Tc). This first reported behavior resembles that ferromagnetic clusters.
