摘要：

We have successfully grown epitaxial, superconducting films of Ba(Fe1-xCox)(2)As-2 ( Ba-122) with x similar to 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 J(c)(theta). In contrast to cuprate high-T-c superconductors such as YBa2Cu3O1-delta or even Bi2Sr2Ca2Cu3O10-delta, the pnictides show a rather low anisotropic behavior in their J(c)(theta) behavior as well as in their upper critical fields, H-c2. As a multiband superconductor, Ba-122 exhibits a temperature dependent electronic mass anisotropy.
