Electronic structure of new LiFeAs high-Tc superconductor

We present results of ab initio LDA calculations of electronic structure of next generation layered iron-pnictide high-T (c) superconductor LiFeAs (T (c) = 18 K). Obtained electronic structure of LiFeAs very similar to recently studied ReOFeAs (Re = La, Ce, Pr, Nd, Sm) and AFe(2)As(2) (A = Ba, Sr) compounds. Namely close to the Fermi level its electronic properties are also determined mainly by Fe 3d-orbilats of FeAs4 two-dimensional layers. Band dispersions of LiFeAs are very similar to the LaOFeAs and BaFe2As2 systems as well as the shape of the Fe-3d density of states and Fermi surface.
