Negative dielectric constant (NDC) materials have the potential for unique optical and microwave applications and their use can greatly reduce the complexity of device architecture. The observation of temperature‐dependent NDC above 503 K in the perovskite PrMnO₃ is reported which obeys the classical Drude theory. This is confirmed through impedance spectroscopy, and the principle behind the associated negative dielectric loss is explained using the Axelrod mechanism.

钙钛矿型PrMnO3的负介电常数转换

负介电常数（NDC）材料具有独特的光学和微波应用潜力，其使用可以大大降低器件架构的复杂性。据报道，在钙钛矿PrMnO _3中观察到了503 K以上随温度变化的NDC，这符合经典的Drude理论。这可以通过阻抗光谱法得到证实，并使用Axelrod机理解释了相关的负介电损耗的原理。
