抜粋

Bulk superconductivity was discovered in BaRh2P2 (Tc=1.0K), BaIr2P2 (Tc=2.1K) and SrIr2As 2 (Tc=2.9K), which are isostructural to (Ba,K)Fe2As 2, indicative of the appearance of superconductivity over a wide variety of layered transition metal pnictides. The electronic specific heat coefficient in the normal state, 9.75, 6.86 and 7.03 mJ/(mol K2) for BaRh2P2, BaIr2P2 and SrIr 2As2 respectively, indicate that the electronic density of states of these three compounds are moderately large but smaller than those of Fe pnictide superconductors.
