Abstract
Utilizing magnetic heating, calorimetric measurements of the latent heat of transition of superconducting lead were made in the temperature range 2.5°K to 7.0°K. The values obtained demonstrate the inadequacy of the assumption of a parabolic or cubic critical magnetic field for lead, but are consistent with the assumpttion of a quartic critical field approximation. The latent heat data obtained are used to derive expressions for the normal and superconducting electronic specific heat.Keywords
