Structural Distortion Stabilizing the Antiferromagnetic and Semiconducting Ground State of BaMnAs
Ekkehard Krüger
We report evidence that the experimentally found antiferromagnetic structure as well as the semiconducting ground state of BaMnAs are caused by optimally-localized Wannier…
Structural distortion in antiferromagnetic BaFe2As2 as a result of time-inversion symmetry
Ekkehard Krüger, Horst P. Strunk
As reported by Q. Huang et al. [Phys. Rev. Lett. 101, 257003 (2008)], neutron diffraction studies show an onset of antiferromagnetic order in BaFe2As2 associated with a tetragonal-…
Structural distortion as prerequisite for superconductivity in LiFeAs
Ekkehard Krüger, Horst P. Strunk
The nonadiabatic Heisenberg model predicts a structural distortion in LiFeAs below a temperature higher than (or at least equal to) the superconducting transition temperature. With…
The reason why doping causes superconductivity in LaFeAsO
Ekkehard Krüger, Horst P. Strunk
The experimental observation of superconductivity in LaFeAsO appearing on doping is analyzed with the group-theoretical approach that evidently led in a foregoing paper (J. Superco…
The structural distortion in antiferromagnetic LaFeAsO investigated by a group-theoretical approach
Ekkehard Krüger, Horst P. Strunk
As experimentally well established, undoped LaFeAsO is antiferromagnetic below 137K with the magnetic moments lying on the Fe sites. We determine the orthorhombic body-centered gro…
Theoretical investigation of the magnetic structure in YBa_2Cu_3O_6
Ekkehard Krüger
As experimentally well established, YBa_2Cu_3O_6 is an antiferromagnet with the magnetic moments lying on the Cu sites. Starting from this experimental result and the assumption, t…
