Abstract
In the high temperature cuprate superconductor, HgBa2CuO4+δ, it has been determined that the dopant oxygen, Oδ, resides in the Hg-plane. Here 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 Oδ atoms. Additionally, we have measured a linear dependence of the peak frequencies on doping and suggest that these measurements might be theoretically amenable.
