使用新出现的电磁邻近效应的理论模型，我们证明，它提供了一个很好的描述我们以前报道的异常迈斯纳屏蔽薄膜超导铁磁邻近结构中观察到的。利用低能μ子自旋旋转测量技术，我们通过直接探测各种超导体-铁磁体邻近结构中的磁通屏蔽来进一步研究这一新理论。我们研究其主要特点，并发现一般良好的理论和实验之间的协议。理解和控制这种新的邻近效应是迈向新一代超导自旋电子器件的重要一步。
Using the newly emerged theory model of an electromagnetic proximity effect, we demonstrate that it provides a good description of our previously reported anomalous Meissner screening observed in thin film superconductor-ferromagnet proximity structures. Using the low energy muon spin rotation measurement technique, we further investigate this new theory by probing directly the flux screening in various superconductor-ferromagnet proximity structures. We examine its main characteristics and find in general good agreement between theory and experiment. Understanding and control of this new proximity effect is an important step forward toward a new generation of superconducting spintronic devices.
