Abstract

The multiferroic Bi_0.9Ca_0.1FeO₃, Bi_0.9Ca_0.1Fe_0.9Co_0.1O₃, Bi_0.9Ca_0.1Fe_0.9Ni_0.1O₃, Bi_0.9Ca_0.1Fe_0.9Cu_0.1O₃ samples were prepared by a simple sol–gel method. Rietveld refinement of X-ray diffraction data and Raman spectra reflect a structural phase transition from single phase (rhombohedral, pure BiFeO₃) to two phase coexistence (rhombohedral R3c and cubic Fm-3 m). The structural distortion of Bi_0.9Ca_0.1Fe_0.9Ni_0.1O₃ is very marked. SEM images show the co-doped nanoparticles having an average size of 50 nm. A contribution from the leakage current have been observed in the P–E loops. XPS results reveal that the concentration of Fe²⁺ and oxygen vacancy decreased after transition metal elements (Co, Ni, Cu) doped into Bi_0.9Ca_0.1FeO₃. Moreover Co, Ni doping can enhance the saturation magnetization, while Cu doping can enhance the coercive field in Bi_0.9Ca_0.1FeO₃.
