The superconductivity at 18 K in LiFeAs system
arXiv:0806.4688 · doi:10.1016/j.ssc.2008.09.057
Abstract
A new iron arsenide superconducting system LiFeAs was found that crystallizes into a tetragonal structure with space group P4/nmm. The superconductivity with Tc up to 18 K was observed in the compounds. This simple 111 type layered iron arsenide superconductor can be viewed as an analogue of the infinite layer structure of copper oxides.
