  • Descrição: There has been a tendency for micro-cracks to be generated in superconducting films deposited on R-Al2O3 substrates with buffer layers. Thickening the buffer layer is one method for suppressing the generation of micro-cracks. When Sm2O3 buffer layers were thickened, surface roughness (Rz) of Sm2O3 and EuBa2Cu3O7 (EBCO) films increased and the critical current density (Jc) deteriorated with increase in Sm2O3 buffer layer thickness (tSm). Then, the improvement of Sm2O3 buffer layers on surface morphology and increment of Jc of EBCO thin films deposited on the thick Sm2O3 buffer layers were carried out. The surface roughness (Rz) of Sm2O3 buffer layers became small by optimizing sputtering conditions. Rz of EBCO thin films decreased depending on that of Sm2O3 buffer layers. The critical temperature (Tce) was 90K and Jc showed a high value of 1.6MA/cm2 at 77.3K when tSm was 2000Å.
