Two IF peaks correspond well with two resistance peaks. Combing the results of electric and magnetic measurements, we think the high temperature IF peak corresponds to a transition from paramagnetic rhombohedral to ferromagnetic rhombohedral, and we can explain it with mechanism of double exchange. Whereas the low temperature IF peak is complicated, at which no apparent magnetic transition appears. We interpret it as a combination of a lattice distortion caused by a phase transition from ferromagnetic rhombohedral to ferromagnetic orthorhombic and a phase separation separating out an ordered ferromagnetic insulator polar phase at low temperature.
两个电阻峰与内耗峰出现的位置有较好的对应关系，结合磁化率测量的结果，我们定性的解释高温电阻峰起因于顺磁斜方相到铁磁斜方相的转变，是由磁性转变所引起的，符合双交换机制；而低温电阻峰情况较为复杂，无明显磁性转变，不能用双交换机制解释，被理解为由两方面的因素所致：即从铁磁斜方相到铁磁正方相的转变所引起的点阵畸变；低温下相分离所产生的铁磁绝缘体极化子有序相的综合结果。

The structure measurement indicates that only a small amount of Bi3+ ions can not enter the A-site of La2/3Ca1/3MnO3 lattice. Because of the low melting behavior of bismuth oxide, the superfluous Bi will segregate as insulating bismuth oxides and bismuthate. Because of the segregation of Bi, the surface of the main phase has different ferromagnetic property from that of the core, namely the magnetic inhomogeneity of the samples is enhanced, which results in the broader ferromagnetism-paramagnetism transition and magnetoresistance plateaus in samples with the high Bi content.
