摘要:

极化中子反射仪(PNR)提供的证据表明,非局域电动力学支配的磁场渗透在一个极端的低k超导体。该样品是一个大的弹性平均自由程(11 mkm)沉积在氧化硅晶片上的铟膜。结果表明,PNR可以解决由局域和非局域超导理论预测的反射中子自旋不对称性之间的差异。实验数据支持非局域理论,该理论预言了磁场的非单调衰减。

英文摘要:

Polarized neutron reflectometry (PNR) provides evidence that nonlocal electrodynamics governs the magnetic field penetration in an extreme low-k superconductor. The sample is an indium film with a large elastic mean free path (11 mkm) deposited on a silicon oxide wafer. It is shown that PNR can resolve the difference between the reflected neutron spin asymmetries predicted by the local and nonlocal theories of superconductivity. The experimental data support the nonlocal theory, which predicts a nonmonotonic decay of the magnetic field.
