Title: Evidence for intrinsic impurities in the high-temperature superconductor Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} from {sup 17}O nuclear magnetic resonance.

Journal Article · · Phys. Rev. B

We have found that high quality crystals of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} (Bi-2212) have intrinsic magnetic defects that depend on oxygen doping. Our {sup 17}O nuclear magnetic resonance spectra provide evidence that local moments form in the CuO{sub 2} 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.
