超导薄膜迈斯纳电流的金刚石磁测量
Diamond Magnetometry of Meissner Currents in a Superconducting Film
摘要：
研究了磁场对超导铌薄膜的穿透作用。磁场的成像是通过光学检测单晶金刚石内部带负电荷的氮空位缺陷的磁共振来进行的，所述单晶金刚石附着在所研究的铌膜上。将实验结果与基于临界态模型的理论预测进行了比较，得到了很好的一致性。
英文摘要：
We study magnetic field penetration into a thin film made of a superconducting niobium. Imaging of magnetic field is performed by optically detecting magnetic resonances of negatively charged nitrogen-vacancy defects inside a single crystal diamond, which is attached to the niobium film under study. The experimental results are compared with theoretical predictions based on the critical state model, and good agreement is obtained.
