摘要

The specific heat of single crystal hole-doped Ca_0.33Na _0.67Fe₂As₂, Tconset=33.7 K, was measured from 0.4 to 40 K. The discontinuity in the specific heat at T_c, ΔC, divided by T_c is 105±5 mJ/mol K², consistent with values found previously for hole-doped Ba_0.6K_0.4Fe ₂As₂ and somewhat above the general trend for ΔC/T_c vs T_c for the iron based superconductors established by Bud'ko, Ni and Canfield. The usefulness of measured values of ΔC/T_c as an important metric for the quality of samples is discussed.
