文摘：本文报道了在YBa2Cu3O7-δ薄膜和两种La2-xSrxCuO4薄膜中，当温度接近正常-超导体转变温度时，偏置正弦电流在几条带状图案上产生的三次谐波电压响应的尖峰。研究了三次谐波信号对电流特性的拉姆达型温度依赖性。研究了三次谐波产生的几种物理机制。
Abstract:In this paper, we report on the sharp peak observed in the third harmonic voltage response generated by a bias sinusoidal current applied to several strips patterned in a YBa2Cu3O 7 - δ thin film and in two La2-xSrxCuO4 thin films, when the temperature is close to the normal-superconductor transition. The lambda-shaped temperature dependence of the third harmonic signal on the current characteristics is studied. Several physical mechanisms of third harmonic generation are examined.
