Structure of HgBa2CuO4+delta (0.06

Abstract:

The results of a neutron-diffraction study of the HgBa2CuO4+δ structure at ambient pressure and under external pressure at different extra oxygen concentrations are presented. The results have been analyzed together with the data of previous investigations. It is shown that in the cation-stoichiometric samples the Oδ oxygen is only present in the center of the mercury layer, Tc is parabolically dependent on δ, and Tc,max is obtained at δopt=0.13±0.01. The influence of pressure on the structur...
