Electric noise spectroscopy is a non-destructive and a very sensitive method for studying the dynamic behaviors of the charge carriers and the kinetic processes in several condensed matter systems, with no limitation on operating temperatures. This technique has been extensively used to investigate several perovskite compounds, manganese oxides (La_1−xSr_xMnO₃, La_0.7Ba_0.3MnO₃, and Pr_0.7Ca_0.3MnO₃), and a double perovskite (Sr₂FeMoO₆), whose properties have recently attracted great attention. In this work are reported the results from a detailed electrical transport and noise characterizations for each of the above cited materials, and they are interpreted in terms of specific physical models, evidencing peculiar properties, such as quantum interference effects and charge density waves.

电噪声光谱学可以告诉我们钙钛矿的物理性质吗？

电噪声光谱学是一种无损且非常灵敏的方法，用于研究几种冷凝物系统中电荷载流子的动力学行为和动力学过程，而对工作温度没有限制。该技术已广泛用于研究几种钙钛矿化合物，锰氧化物（La _{1- x} Sr _x MnO ₃，La _0.7 Ba _0.3 MnO ₃和Pr _0.7 Ca _0.3 MnO ₃）和双钙钛矿（Sr ₂ FeMoO _6）），其特性最近引起了极大的关注。在这项工作中，报告了上述每种材料的详细电传输和噪声表征的结果，并根据特定的物理模型进行了解释，这些物理模型具有特殊的性质，例如量子干扰效应和电荷密度波。
