Synthesis and structure of SrCo2Si2 and CaRh2Si2 - isoelectronic variants of the parent superconductors AeFe2As2 and study of the influence of the valence electron count in CaFe2-xRhxSi2

Andrea V. Hoffmann, Viktor Hlukhyy, Thomas F. Fässler

The finding of superconductivity in Ba0.6K0.4Fe2As2 put the attention on the investigation of compounds that crystallize with ThCr2Si2 structure type such as AT2X2 (A = alkali/ alk…
