We report an analysis of the dielectric glasslike state of the spin- and charge-ordered system Lu₂Fe₃O₇, which has structural and physical properties analogous to those of the electronic ferroelectrics RFe₂O₄ (R: rare earth). Aging and memory effects of resistivity were found in the electric impedance response. We performed a numerical analysis with equivalent electric circuits that have a logarithmic Gaussian distribution of resistance and capacitance. The distribution parameters well explained the glassy nature of the electric and dielectric properties between 100 and 200 K and the distribution variations of charge- and magnetic-ordered domains underlying the glass nature.

分布等效电路模型分析Lu2Fe3O7的玻璃行为

我们报告了对自旋和电荷有序系统Lu ₂ Fe ₃ O ₇的介电玻璃状状态的分析，该结构具有与电子铁电体R Fe ₂ O ₄（R：稀土）。在电阻抗响应中发现了电阻率的老化和记忆效应。我们对等效电路进行了数值分析，等效电路具有电阻和电容的对数高斯分布。分布参数很好地解释了100至200 K之间的电和介电性质的玻璃态性质，以及玻璃性质背后的电荷和磁有序畴的分布变化。
