AFe2As2 (A = Ca, Sr, Ba, Eu) and SrFe2-xTMxAs2 (TM = Mn, Co, Ni): crystal structure, charge doping, magnetism and superconductivity
Deepa Kasinathan,Alim Ormeci,Katrin Koch,Ulrich Burkhardt,Walter Schnelle,Andreas Leithe-Jasper,Helge Rosner +6 more
TL;DR: In this article, the relationship between the crystal structure, charge doping and magnetism in AFe2As2 systems was analyzed using first-principle band structure calculations, and the tetragonal to orthorhombic structural distortion along with the associated magnetic order and anisotropy, the influence of doping on the A site and the Fe site were analyzed.
Journal ArticleDOI
AFe2As2 (A = Ca, Sr, Ba, Eu) and SrFe_(2-x)TM_(x)As2 (TM = Mn, Co, Ni): crystal structure, charge doping, magnetism and superconductivity
Deepa Kasinathan,Alim Ormeci,Katrin Koch,Ulrich Burkhardt,Walter Schnelle,Andreas Leithe-Jasper,Helge Rosner +6 more
TL;DR: In this article, the relationship between the crystal structure, charge doping and magnetism in pnictide compound systems was investigated using first-principle band structure calculations, and it was shown that the effect of charge doping on the electronic structure of these systems can be seen as a function of the As $z$ position.
Journal ArticleDOI
CeRuPO: A rare example of a ferromagnetic Kondo lattice
Cornelius Krellner,N. S. Kini,E. M. Brüning,Katrin Koch,Helge Rosner,Michael Nicklas,Michael Baenitz,C. Geibel +7 more
TL;DR: In this paper, the physical ground state properties of the compounds CeRuPO and CeOsPO were determined by means of magnetic susceptibility, specific heat, electrical resistivity, and thermopower measurements.
Journal ArticleDOI
75As nuclear magnetic resonance study of antiferromagnetic fluctuations in the normal state of LiFeAs
Peter Jeglič,Anton Potočnik,Martin Klanjšek,Matej Bobnar,Marko Jagodič,Katrin Koch,H. Rosner,Serena Margadonna,Bing Lv,Arnold M. Guloy,Denis Arčon +10 more
TL;DR: In this article, a detailed study of the nuclear magnetic resonance Knight shift and spin-lattice relaxation rate in the normal state of stoichiometric polycrystalline LiFeAs is presented.
Journal ArticleDOI
Electronic structure, chemical bonding, and solid-state NMR spectroscopy of the digallides of Ca, Sr, and Ba.
Frank Haarmann,Katrin Koch,Daniel Grüner,Walter Schnelle,Oliver Pecher,Raul Cardoso-Gil,Horst Borrmann,Helge Rosner,Yuri Grin +8 more
TL;DR: Combined application of (69,71)Ga NMR spectroscopy and quantum mechanical calculations reveals the chemical bonding in the digallides of Ca, Sr, and Ba and shows honeycomb-like 6(3) nets of the Ga atoms as the most prominent structural features.
