Phase diagrams of Ca(Fe,Ru)2As2 system — •Kan Zhao and Philipp Gegenwart — Experimentalphysik VI, Elektronische Korrelationen und Magnetismus, Institut für Physik, Universität Augsburg, D-86135 Augsburg, Germany

Single crystalline Ca(Fe,Ru)2As2 series have been grown and characterized by structural, magnetic, and transport measurements. These measurement shows Ca(Fe,Ru)2As2 undergoes successive phase transitions with increasing Ru element doping. The antiferromagnetic phase with orthorhombic structure at x<0.023 (x means the doping concentration of Ru element) is directly driven to a Fermi-liquid type collapsed tetragonal (cT) phase at 0.023<x<0.07, with no superconducting region between the two phase, consistent with the conclusion of CaFe2As2 under hydrostatic pressure.
