“…The two primary approaches are (1) to involve a textured metal substrate to start with, i.e., rolling-assisted biaxially textured substrates (RABiTS) [5] and (2) to build an epitaxial template on amorphous buffered metal substrates called ion-beam-assisted deposition (IBAD) substrates [6][7][8]. Moreover, several film growth techniques have been successfully tailored for the deposition of YBCO thin films with high epitaxial quality on these metal substrates, such as metal-organic chemical vapor deposition (MOCVD) [9,10], pulsed laser deposition (PLD) [11][12][13], metal-organic deposition (MOD) [14,15] as well as magnetron sputtering [16,17]. With over a decade of development, superconducting properties of YBCO coated conductors have been significantly improved and practical applications have been demonstrated in multiple areas such as HTS coated conductors, superconductor magnets, generators and fault current limiters.…”

Vertically aligned nanocomposite (VAN) (La 0.7 Sr 0.3 MnO 3) 0.5 (CeO 2) 0.5 and pure La 0.7 Sr 0.3 MnO 3 layers were incorporated into YBa 2 Cu 3 O 7-δ (YBCO) thin films as bilayer stacks for magnetic flux pinning enhancement. The films show high epitaxial quality, suggested by XRD and TEM study. The critical temperature T c of the bilayers is about 90 K, which is close to that of pure YBCO films, while both the self-field J c sf and in-field critical current density J c in-field are largely enhanced. Among all samples, the film with VAN cap layer shows the highest J c values in all field ranges. This study demonstrates an effective way towards the tunable pinning effect for YBCO coated conductors by both defect and magnetic pinning.
