Abstract

We have synthesized a new layered iron-pnictide CuFeSb. This material shares a similar layered tetragonal structure with iron-based superconductors, with Fe square planar sheets forming from the edge-sharing iron antimony tetrahedral network. CuFeSb differs remarkably from Fe-based superconductors in the height of anion Z anion from the Fe plane; Z Sb for CuFeSb is �1.84 �, much larger than Z As (1.31-1.51 �) in FeAs compounds and Z Te (�1.77 �) in Fe 1+yTe. In contrast with the metallic antiferromagnetic (AFM) or superconducting state of iron pnictides and chalcogenides under current studies, CuFeSb exhibits a metallic, ferromagnetic (FM) state with T c=375 K. This finding suggests that the competition between AFM and FM coupling may exist in Fe-based superconductors and that the nature of magnetic coupling within the Fe plane is indeed dependent on the height of anion as predicted in theories. © 2012 American Physical Society.
