论文摘要
我们使用20 nm厚的超导A-MOGE薄膜中的低频两层互感测量提取涡旋晶格参数。我们使用Coffey和Clem开发的模型符合混合状态中AC穿透深度的温度依赖性，并展示了一种提取涡旋晶格参数的过程，例如固定常数，涡旋晶格阻力系数和固定潜在的屏障。我们表明，提取的参数遵循弱固定的二维涡流晶格预期的磁场变化。
We extract the vortex lattice parameters using low-frequency two-coil mutual inductance measurements in a 20-nm-thick superconducting a-MoGe thin film. We fit the temperature dependence of ac penetration depth in the mixed state using a model developed by Coffey and Clem and demonstrate a procedure for extracting vortex lattice parameters such as pinning constant, vortex lattice drag coefficient, and pinning potential barrier. We show that the extracted parameters follow the magnetic field variation expected for a weakly pinned 2-dimensional vortex lattice.
