Abstract
The c‐axis oriented YBa2Cu3O x (YBCO)film has been epitaxially grown on Y2O3 (001) substrates by in situ processing for the first time to our knowledge. The in‐plane orientation relationship between YBCO and Y2O3 is 〈110〉YBCO∥〈100〉Y2O3. The film exhibits, as deposited, T 0 C =86.2 K, ΔT=1.2 K; J C =1.4×107 and 2.0×106 A/cm2 in a magnetic field of 0 and 5 T at 5 K, respectively. Moreover, the interface between the YBCO and Y2O3 is very sharp and chemically stable.Keywords
