绝缘电阻

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.

结构测试表明Bi并不能进入La2/3Ca1/3MnO3的晶格锰位，由于A位元素的过量和铋氧化物的低熔点特性，烧结过程中Bi元素析出形成了绝缘性的第二相；并且Bi的析出导致样品主相的表面存在与主相体心磁性质不同的铁磁相，即样品的磁不均匀性增强，使得高Bi含量的样品表现出宽的铁磁-顺磁转变和磁电阻平台效应。
