We show from muon spin relaxation (mu SR) studies on mercury HTS super
conductors that a 50-fold increase in irreversibility field obtained b
y partial substitution of Re for Hg is due to metallisation of the Hg/
Re layer. Induced superconductivity on this metallic layer doubles the
overall superfluid density. This suggests a new approach to the desig
n of high performance HTS materials: metallising one of the non-CuO2 i
nterlayers and thereby greatly enhancing the superconducting propertie
