Fluorinated Hg-1223 under pressure: The ultimate Tc of the cuprates?

High pressure experiments have revealed that Tc is affected by two main pressure-dependent parameters: the doping level of the CuO2 planes and by an intrinsic factor. The origin of the intrinsic factor is still unclear as, depending on the experiment, it is associated with the reduction of the c or...
