THE ELECTRONIC PROPERTIES OF NEW Fe-BASED SUPERCONDUCTORS

Abstract

We investigate the band structure of Fe-based superconductors using the firstprinciple method of density-functional theory. We calculated the band structure and the density of states at the Fermi level for ReFeAsO (Re = Sm, Dy, Ho, Er) superconductors. Our calculations indicate that the maximum critical superconducting transition temperature Tc will be observed for compounds with Sm and Er. We predict that Tc = 60K for ErFeAsO.

Keywords:

Fe-based superconductors, band structure, density of states, critical superconducting transition temperature
