Title: Location of the Oxygen dopant in the high temperature superconductor HgBa 2CuO 4 + δ from 199Hg NMR

Abstract

In the high temperature cuprate superconductor, HgBa 2CuO 4 + δ , , it has been determined that the dopant oxygen, O δ, resides in the Hg-plane. We present a systematic investigation of the 199Hg NMR spectrum as a function of dopant oxygen concentration, δ. At high doping levels we observe four distinct 199Hg resonance peaks which follow a binomial distribution in δ corresponding to zero, one, two, and three nearest neighbor O δ atoms. Finally and additionally, we have measured a linear dependence of the peak frequencies on doping and suggest that these measurements might be theoretically amenable.
