Abstract

The superconducting properties of a recently identified high-pressure dhcp phase of Pb-Bi have been studied. There is a small abrupt drop in the superconducting transition temperature from 8.43 to 7.96 K as the samples transform from the mixed α-β phase to the dhcp phase. Both the mixed α-β phase and the dhcp phase show a surprisingly small negative slope for the volume dependence of the superconducting transition temperature corresponding tod(lnT c )/d(lnV)=0.39.
