摘要：

Microwave-stimulated flux nucleation has been observed in an artifical superconducting loop with Josephson junctions formed by pressing lead pieces together. A regular series of microwave absorption lines similar to those seen in niobium, indium, and single crystals of Y-Ba-Cu-O is obtained. The separation of the first derivative of the absorption lines indicates a band of microwave absorption that is proportional to the square root of the microwave power and has a definite threshold power. A simple model based on that of Silver and Zimmerman is used to explain the data. A superconducting path with two weak links is assumed with flux entering the junction when microwaves drive the junction normal. © 1990 The American Physical Society.
