论文摘要
在先前的研究中，非中心对称超导体ru $ _7 $ _3 $在其涡旋晶格中表现出非常不寻常的行为，在那里，涡流的最接近涡流的邻居方向与水晶晶格分离，而是显示了一个复杂的现场历史依赖性，并且涡旋晶格旋转既已变化。在这项研究中，我们查看在这种现场历史依赖期间的涡旋晶格形式$ _7 $ b $ _3 $，以检查与既定模型（例如伦敦车型）的偏差。我们发现数据由各向异性伦敦模型很好地描述，这与理论上的预测一致，即由于反转对称性破裂而导致的涡流结构的改变应该很小。由此，我们还提取了穿透深度和相干长度的值。
The noncentrosymmetric superconductor Ru$_7$B$_3$ has in previous studies demonstrated remarkably unusual behaviour in its vortex lattice, where the nearest neighbour directions of the vortices dissociate from the crystal lattice and instead show a complex field-history dependence, and the vortex lattice rotates as the field is changed. In this study, we look at the vortex lattice form factor of Ru$_7$B$_3$ during this field-history dependence, to check for deviations from established models, such as the London model. We find that the data is well described by the anisotropic London model, which is in accordance with theoretical predictions that the alterations to the structure of the vortices due to broken inversion symmetry should be small. From this, we also extract values for the penetration depth and coherence length.
