Specific heat of the superconducting high pressure phase Ga II

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

The high pressure modification gallium II, which becomes superconducting near 6.4 K, has for the first time been investigated calorimetrically at about 35 kbar in the temperature range of liquid helium. From the data a Debye temperatureΘ D = 178K and an electronic specific-heat coefficient γ=1.75 mJ/mole K2 are obtained. These values are in good qualitative accord with the increased superconductingT c with respect to that of Ga I.
