“…One obtains H~ as a function of temperature as usual from the entropy difference AS and then from the free energy difference AG, which are defined, respectively, by fT cC"(T) dT (19) (20) We have used the observed values of Cs(T) and the calculated values of C,(T) in the last subsection. Figure 5 shows the Hc vs. T curve.…”

Thermodynamic study and intrinsic type II superconductivity in the A-15 compound V3Si

et al. 1979

The specific heat of a single crystal of the A-15-type compound V3Si in the normal, mixed, and superconducting states has been measured from 4 to 30 K in magnetic fields up to 50 kOe. The analysis has been performed in a self-consistent way based on the second-order phase transition from the normal to the superconducting state. The thermodynamic critical field and then various physical parameters characterizing the superconducting and normal states are almost consistently derived from the thermodynamics and the microscopic BCS-GLA G theory. It is confirmed that V3Si is an intrinsic type H superconductor with a high intrinsic GL parameter Ko.
