Abstract: | The future fabrication of high-temperature-superconductor-based coated conductors depends on the current research of thin films’ growth processes, especially in developing low cost, scalable and industrially processing methods. A new transient liquid assisted growth method is explored through the growth of 𝑌𝐵𝑎$𝐶𝑢'𝑂) − 𝐵𝑎𝑍𝑟𝑂' and 𝑌𝐵𝑎$𝐶𝑢'𝑂)thin films. The characterization of spin-coating deposed thin films verified c-axis epitaxy, although the presence of secondary phases within the film were also confirmed. 𝐵𝑎𝑍𝑟𝑂' nanoparticles proved to be useful to enhance density superconducting properties at high fields, furthermore a 1.77 MA cm-2 current density was achieved for 𝑌𝐵𝑎$𝐶𝑢'𝑂) − 𝐵𝑎𝑍𝑟𝑂' films at 5 K, whereas for lesser fields 𝑌𝐵𝑎$𝐶𝑢'𝑂) current density was up to 19.94 MA cm-2 also at 5 K. Critical temperatures of (89.2 ± 0.6)K and (90.6 ± 0.4) K were obtained for the films, respectively. First steps towards a new combinational chemistry approach for the inkjet printed samples were also performed |
