NMR relaxation time around a vortex in stripe superconductors

Abstract

Site-dependent NMR relaxation time $T_1(\mathbf{r})$ is calculated in the vortex state using the Bogoliubov-de Gennes theory, taking account of possible "field-induced stripe'' states in which the magnetism arises locally around a vortex core in d-wave superconductivity. The recently observed huge enhancement $T_1^{-1}(\mathbf{r})$ below $T_c$ at a core site in Tl${}_2$Ba${}_2$CuO${}_6$ is explained. The field-induced stripe picture explains consistently other relevant STM and neutron experiments.
