A new pnictide superconductor without iron.
LiCu(2)P(2) and LiFeP have been synthesized by conventional solid-state reaction. LiCu(2)P(2) has a crystal structure similar to that of BaFe(2)As(2); LiFeP has the same crystal structure as that of LiFeAs. Resistivity and magnetization measurements reveal that they become superconductive at 3.5 K for LiCu(2)P(2) and 4.1 K for LiFeP.
