Abstract The structural, electrical, magnetic and 57Fe Mossbauer studies of sol-gel synthesized polycrystalline Pr1-xAlxFeO3 (x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5) samples are reported in this paper and the phase purity of the materials was confirmed from Rietveld refinement of XRD pattern. From the magnetization studies it is observed that the Al doping at Pr site changed the magnetic ordering of the system at both room and low temperatures. The observed isomer-shift values from room temperature Mossbauer spectroscopy confirmed the charge state of the Fe ions and magnetic ordering in the compounds. Leakage current is observed to decrease with Al doping in the present work. From the leakage current density (J-E) measurements, it is observed that the space charge limited conduction (SCLC) dominates the conduction in lower and higher field regions for all the samples.

Al 掺杂的 PrFeO 3 多晶材料的电、磁和 57 Fe Mössbauer 研究

摘要 本文报道了溶胶-凝胶合成多晶 Pr1-xAlxFeO3 (x = 0、0.1、0.2、0.3、0.4 和 0.5) 样品的结构、电、磁和 57Fe Mossbauer 研究，并确认了材料的相纯度来自 XRD 图案的 Rietveld 精修。从磁化研究中可以看出，Pr 位点的 Al 掺杂改变了系统在室温和低温下的磁序。从室温穆斯堡尔光谱观察到的异构体位移值证实了 Fe 离子的电荷状态和化合物中的磁性排序。在目前的工作中观察到泄漏电流随着 Al 掺杂而降低。从泄漏电流密度 (JE) 测量结果来看，
