Synthesis and superconducting properties of HgBa2Ca2Cu3O8 +x
Abstract
The influence of precursor composition, nominal mercury vapour pressure (PHg) and reaction temperature (t) on the formation of HgBa2Ca2Cu3O8 +x have been studied. By reducing the empty space inside the quartz tube, we could increase PHg higher than 200 atm and obtain samples containing only HgBa2Ca2Cu3O8 +x as the superconducting phase, with Tc(onset)= 134 K and Tc(zero)= 131 K.
