    Theoretical investigation of the electronic and magnetic properties of the orthorhombic phase of Ba(Fe1?x Cox )2 As2

  • Original language description

    We present a comprehensive study on the low-temperature orthorhombic phase of Ba(Fe1?x Cox )2 As2 based on the Korringa-Kohn-Rostoker-Green function approach. Using this band-structure method in combination with the coherent potential approximation alloytheory we are able to investigate the evolution of the magnetic and electronic properties of this prototype iron pnictide for arbitrary concentrations x, while dealing with the chemical disorder without uncontrolled simplifications by using solely a rigid-band shift or the virtual crystal approximation. We discuss the development of the site-resolved magnetic moments for the experimentally observed stripe antiferromagnetic order together with the strong electronic anisotropy of the Fermi surface and compare it with angle-resolved photoemission spectroscopy measurements of detwinned crystals. We furthermore calculate magnetic exchange coupling parameters Jij and use them for Monte Carlo simulations on the basis of the classical Heisenbe
