Abstract

We report the single crystal growth of Ca(Fe1−x Co x )2As2 (0 ≤ x ≤ 0.082) from Sn flux. The temperature–composition phase diagram is mapped out based on the magnetic susceptibility and electrical transport measurements. The phase diagram of Ca(Fe1−x Co x )2As2 is qualitatively different from those of Sr and Ba; this could be due to both the charge doping and structural tuning effects associated with Co substitution.
