“…It also enables the drop-on-demand ink-jet printing ( Figure 1B) deposition of YBCO nanocomposite thin-films on substrates. This CSD route shows a high potential for low-cost, long-length industrial production (reel-to-reel deposition) on industrial Ni-W tape [36]. This comprehensive study may serve as a generic approach to use ink-jet printing technology for the fabrication of several other electrical, magnetic, and optical nanocomposite thin films.…”

To reduce the fabrication costs while maximizing the superconducting and pinning properties of YBa2Cu3O7−δ (YBCO) nanocomposite films, the drop-on-demand ink-jet printing technique was used to deposit colloidal YBCO inks onto LaAlO3 substrates. These inks containing preformed HfO2 nanocrystals were carefully adjusted, prior to the jettability, as the droplet formation depends on the rheological properties of the inks themselves. After carefully adjusting printing parameters, 450-nm thick pristine YBCO films with a self-field critical current density (Jc) of 2.7 MA cm−² at 77 K and 500-nm thick HfO2-YBCO nanocomposite films with a self-field Jc of 3.1 MA·cm−² at 77 K were achieved. The final HfO2-YBCO nanocomposite films contained dispersed BaHfO3 particles in a YBCO matrix due to the Ba2+ reactivity with the HfO2 nanocrystals. These nanocomposite films presented a more gradual decrease of Jc with the increased magnetic field. These nanocomposite films also showed higher pinning force densities than the pristine films. This pinning enhancement was related to the favorable size and distribution of the BaHfO3 particles in the YBCO matrix.

“…Therefore, artificial pinning centres are incorporated as nano-sized defects in the REBCO matrix to achieve the immobilization of vortices, enhancing in-field Ic as well as its isotropy [4][5][6][7]. For CSD-grown REBCO nanocomposites, the pinning centres can be introduced via spontaneous segregation of nanoparticles (in-situ approach [8][9][10]) or starting from preformed nanocrystals (ex-situ approach [11,12]). The latter approach, which starts from colloidal solutions, promises better control of the particle size distribution than the usual method of self-assembled nanoparticles [13][14][15][16].…”

We report a successful fabrication of long-length RABiTS-based coated conductors (CC) via chemical solution deposition starting from colloidal YBa2Cu3O7-δ (YBCO) solutions containing 5 mol-% preformed BaMO3 (M = Hf, Zr) nanocrystals. Partial optimization of the existing continuous reel-to-reel YBCO processing via design of experiments (DoE) approach allowed us to obtain YBCO nanocomposites that retain 80-90% self-field performance of the pristine CC and show a 10 to 40% improvement of in-field critical current, which is only a moderate performance improvement compared to similar films on single-crystal substrates prepared on lab-scale. Based on XRD and TEM studies, we attribute this to worsening of the YBCO texture and strong coarsening of BMO nanoparticles, particularly, BaZrO3, during processing. Possible process improvements to overcome these effects are discussed.
