Characterization of REBCO films and tapes towards energy applications.

REBCO tapes are being manufactured by multiple companies using unique combinations of materials and deposition processes. To effectively design and use them in power devices, it is important to determine their critical fields and flux pinning characteristics. In this work, electrical transport measurements were performed on commercially available coated conductors. Magneto-resistivity measurements were taken at various angles between coated conductor sample and magnetic field up to 15 T. We determined the flux pinning energy and highlighted its noticeable increase related to the intrinsic contribution of the REBCO lattice structure when a magnetic field is applied parallel to the $ab-plane$. We compared the results of our determination on commercial tapes with the results obtained on films deposited through chemical solution deposition on single crystal substrates. Furthermore, we measured the critical currents of full-size 4 mm wide conductors across a large field range at 4.2 K under the perpendicular applied magnetic field.
