dc.description.abstractAlthough high temperature superconductors are promising for power applications, the production of low-cost coated conductors with high current densities—at high magnetic fi elds—remains challenging. A superior superconducting YBa 2 Cu 3 O 7–δ nanocomposite is fabricated via chemical solution deposition (CSD) using preformed nanocrystals (NCs). Preformed, colloidally stable ZrO 2 NCs are added to the trifl uoroacetic acid based precursor solution and the NCs’ stability is confi rmed up to 50 mol% for at least 2.5 months. These NCs tend to disrupt the epitaxial growth of YBa 2 Cu 3 O 7–δ , unless a thin seed layer is applied. A 10 mol% ZrO 2 NC addition proved to be optimal, yielding a critical current density J C of 5 MA cm −2 at 77 K in self-fi eld. Importantly, this new approach results in a smaller magnetic fi eld decay of J C (H//c) for the nanocomposite compared to a pristine fi lm. Furthermore, microstructural analysis of the YBa 2 Cu 3 O 7–δ nanocomposite fi lms reveals that different strain generation mechanisms may occur compared to the spontaneous segregation approach. Yet, the generated nanostrain in the YBa 2 Cu 3 O 7–δ nanocomposite results in an improvement of the superconducting properties similar to the spontaneous segregation approach. This new approach, using preformed NCs in CSD coatings, can be of great potential for high magnetic fi eld applications.es_ES
