Fig. 1. XRD diffractograms of a) the pre-mixture Y2O3, CuO and BaCaO3 powders and their sintering at 850 °C and 950 °C and b) printed samples A (sintered at 950 °C) and C (YBCO powder annealed at 450 °C). Fig. 2. SEM and EDS analysis of mixed powder (a), YBCO powder (b), printed samples A (c) and (d) and printed samples C (e) and (f). Fig. 3. Raman spectra taken from four different spots on the surfaces of samples A and C. The spots are marked in the corresponding microscope images, and their colours match the spectra colours.

(a) The temperature dependence of magnetization, showing the zero-field-cooling (ZFC) and field cooling (FC) at an applied magnetic field of 100 Oe. (b) The magnetic field dependence of the magnetization for the A and C samples, taken at 4.2 K and 50 K. (c) The magnetic hy
