摘要：

(1-x)BiFeO3-xBa0.9Ca0.1Ti0.9Sn0.1O3 (0,1 0.9Ca0.1Ti0.9Sn0.1) substitution. These results were confirmed by Raman spectroscopy analysis. Moreover, Ba0.9Ca0.1Ti0.9Sn0.1O3 doped BiFeO3 significantly reduces electric leakage and enhances dielectric properties. The obtained hysteresis loop (M-H) indicates that magnetization was enhanced and the maximum value of remnant magnetization occurred at x = 0.2 with Mr = 0.163 emu/g. This can be explained by the suppression of the cycloid spin structure. A further increase in the substitution percentage beyond the sample x = 0.20 caused a large reduction in residual magnetization due to the dominant participation of collinear antiferromagnetic scheduling in the Pnma space group. © 2017 Elsevier B.V.
