摘要

Single-phase Bi_0.95Ln_0.05Fe_0.95Co _0.05O₃ (Ln = La, Pr) nanoparticles were prepared by sol-gel method. The impurity phase was effectively suppressed, which was confirmed from XRD measurements. Compared with BiFeO₃ (BFO) and BiFe_0.95Co_0.05O₃ prepared under the similar conditions, the magnetic properties of the two co-doped samples were significantly enhanced. Raman results have shown that La and Co co-doping induced significant structure distortion of Fe-O bonds, which may result in a higher value of saturate magnetization, 0.535 emu/g. In addition, the co-doping of La and Co into BFO can reduce the leakage current and enhance the ferroelectric properties.
