Abstract

We report site-selective $^{63}$ Cu NMR studies of the vortex core states of an overdoped Tl $_{2}$ Ba $_{2}$ CuO $_{6 + I^´}$ with $T_{c}$ = 85 K. We observed a relatively high density of low-energy quasi-particle excitations at the vortex cores in a magnetic field of 7.4847 T along the c axis, in contrast to YBa $_{2}$ Cu $_{3}$ O $_{7 - I^´}$ .
