N2 - We have found that high quality crystals of Bi2 Sr2 Ca Cu2 O8+δ (Bi-2212) have intrinsic magnetic defects that depend on oxygen doping. Our O17 nuclear magnetic resonance spectra provide evidence that local moments form in the Cu O2 plane in both normal and superconducting states. We suggest that these magnetic impurities are related to the electronic disorder that scanning tunneling microscopy experiments identify with the oxygen dopant atoms.
