Abstract In this paper, magnetic phase coexistence and magnetotransport properties of Pr0.5–xBixSr0.5MnO3 (x ≤ 0.15) samples have been studied. Our specimens demonstrate complicated magnetic properties through the presence of several transitions as a function of temperature. With increase in bismuth content, a spin–glass–like–state appears at low temperatures and long–range charge ordering can be observed for x = 0.15. Magnetization and resistivity seems to be sensitive to magnetic field cycling, testifying the presence of training effect. Both, magnetic phase separation phenomenon and 6s2 lone pair electrons of Bi3+ ions, play a key role in the governance of the physical response of studied specimens.

多晶 Pr0.5–xBixSr0.5MnO3 (x ≤ 0.15) 中的磁相分离

摘要 本文研究了Pr0.5–xBixSr0.5MnO3 (x ≤ 0.15) 样品的磁相共存和磁输运特性。我们的样品通过作为温度函数的几种转变的存在来展示复杂的磁性。随着铋含量的增加，低温下会出现自旋玻璃状状态，并且可以观察到 x = 0.15 的长程电荷排序。磁化和电阻率似乎对磁场循环敏感，证明了训练效果的存在。磁相分离现象和 Bi3+ 离子的 6s2 孤对电子在研究样品的物理响应的治理中起着关键作用。
