Oxygen ordering in the high-T$_c$ superconductor HgBa$_2$CaCu$_2$O$_{6+\delta}$ as revealed by perturbed angular correlation
Lattice sites and collective ordering of oxygen atoms in HgBa$_2$CaCu$_2$O$_{6+\delta}$ were studied using the perturbed angular correlation (PAC) technique at ISOLDE/CERN. The electric field gradients (EFG) at $^{199m}$Hg nuclei have been measured as functions of oxygen doping on the Hg planes, abo...
