Аннотация:
We present results of ab initio LDA calculations of electronic structure of “next generation” layered ironpnictide High-T$_c$ superconductor LiFeAs (T$_c$=18K). Obtained electronic structure of LiFeAs is 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 3$d$-orbitals of FeAs$_4$ two-dimensional layers. Band dispersions of LiFeAs are very similar to the LaOFeAs and BaFe$_2$As$_2$ systems as well as the shape of the Fe-3$d$ density of states and Fermi surface.
