Site-dependent NMR relaxation time around in the vortex was calculated using Bogoliubov-de Gennes theory. NMR was calculated considering possibility of field-induced stripe states in which magnetism arises locally around a vortex core in d-wave superconductivity. A large enhancement observed in the vortex core site NMR in oxide superconductors was also discussed. It was found that the strength of the induced stripe depends on material's parameters and the field-induced stripe picture explained other relevant STM and neutron experiments.
