We have successfully grown epitaxial, superconducting films of Ba(Fe1-xCox)2As2 (Ba-122)with x ~ 0.1. The films grow without observable correlated defects parallel to the c-axis, as confirmed by TEM. This is also reflected in the absence of a c-axis peak in Jc(θ). In contrast to cuprate high-Tc superconductors such as YBa2Cu3O7-δ or even Bi2Sr2Ca2Cu3O10-δ, the pnictides show a rather low anisotropic...
