arXiv:0911.2394 · doi:10.1016/j.physc.2009.12.040
Abstract
RbFe2As2 has recently been reported to be a bulk superconductor with Tc = 2.6 K in the undoped state, in contrast to undoped BaFe2As2 with a magnetic ground state. We present here the results of the first-principles calculations of the structural, elastic and electronic properties for this newest superconductor and discuss its behaviour in relation to other related systems. Keywords: RbFe2As2, Electronic structure; Elastic constant; Superconductivity. PACS: 74.70.Dd, 74.10.+v, 74.20.Pq, 75.25.Ld
