在Eilenberger理论的基础上，定量地估计了涡旋晶格态中局域核磁共振弛豫率的空间变化，以阐明波超导体与波超导体的区别。我们研究了涡核内外的温度和磁场依赖性，包括玻恩极限和么正极限下的非线性杂质散射的影响。这些结果有助于通过择址核磁共振实验探测涡旋晶格态局域电子结构的细节特征。
On the basis of the Eilenberger theory, spatial variation of the local NMR relaxation rateis quantitatively estimated in the vortex lattice state, to clarify the differences between the-wave and the-wave superconductors. We study the temperature and the magnetic field dependencies ofinside and outside of the vortex core, including influences of nonmagnetic impurity scatterings in the Born limit and in the unitary limit. These results are helpful to detect detailed characters of local electronic structures in the vortex lattice states via site-selective NMR experiments.
