  We report the single crystal growth of Ca(Fe1-xCox)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. Phase
diagram of Ca(Fe1-xCox)2As2 is qualitatively different from those of Sr and Ba,
it could be due to both the charge doping and structural tuning effects
associated with Co substitution.
