BAND STRUCTURE OF RUTHENATE SUPERCONDUCTORS

Abstract

We investigate the band structure of ruthenates using the first-principles method of density functional theory (DFT). We calculated the band structure and density of states at the Fermi level for superconductors Ba₂YRuO₆ and Sr₂YRuO₆. Our calculations show that the maximum critical superconducting transition temperature T_c = 93K can be obtained for Ba₂YRuO₆.
