Inkjet printed multi-deposited YBCO on CGO/LMO/MgO/Y2O3/Al2O3/Hastelloy tape for 2G Coated Conductors

Vlad, Valentina Roxana et al.We present the preparation of a new architecture of coated conductor by Inkjet printing of low fluorine YBa2Cu3O7-x on top of SuperOx tape: CGO/LMO/IBAD-MgO/Y2O3/Al2O3/Hastelloy. A 5-layered multi-deposited, 475 nm thick YBCO film was structurally and magnetically characterized. A good texture was achieved using this combination of buffer layers, requiring only a 30 nm thin IBAD-MgO layer. The LF-YBCO CC reaches self-field critical current density values of JcGB~15.9 MA/cm2 (5 K), ~1.23 MA/cm2 (77 K) corresponding to an Ic(77K)=58.4 A/cm-width. Inkjet printing offers a flexible and cost effective method for YBCO deposition, allowing patterning of structures.This work was performed within the framework of the EUROTAPES project (FP7-NMP.2011.2.2-1 Grant no. 280432), funded by the EU.
