Particularly interesting are the "pinning centers" which reduce the obnoxious magnetic vortices. Down around the critical temperatures (17-23 deg Kelvin), the layered films appear to have outperformed the single film comparison sample and even at room temperature appear to have only one-half of the resistivity (milli-ohm centimeters) of the single film. But, at least as I read the paper, how easily long stretches (e.g., wires) of these materials can be fabricated; how brittle, practical, etc., it would be; how much current carrying ability it would have at the macroscopic level; are engineering points not really discussed.
