63Cu NMR measurements have been carried out in HgBa2Ca2Cu3O8+δ (Hg1223) with the highest transition temperature, Tc = 133 K, to date. The narrow NMR spectrum and the small residual density of states (DOS), Nres, at the Fermi level in the superconducting state indicate that the Hg1223 possesses good quality.
