A New Pnictide Superconductor without Iron
LiCu2P2 and LiFeP have been synthesized by conventional solid-state reaction. LiCu2P2 has a crystal structure similar to that of BaFe2As2; LiFeP has the same crystal structure as that of LiFeAs. Resistivity and magnetization measurements reveal that they become superconductive at 3.5 K for LiCu2P2 and 4.1 K for LiFeP.
