We report on the in situ growth and characterisation of c-axis oriented superconducting YBa2Cu3O7−δ/CeO2 structures deposited on biaxially textured Ni–Cr alloy tapes by respectively thermal and e-beam evaporation. We have studied the effect of growth temperature on the degree of texturing of both CeO2 and YBCO layers. We find that the highest degree of texture of both layers and best superconducting properties with sharp transitions and zero resistance Tc in excess of 85 K are obtained for substrate temperatures during deposition above 700 °C.
