Preparation of a YBCO superconducting tape by pulsed laser deposition
- Huazhong Univ. of Science and Technology, Wuhan (China). National Lab. of Laser Technology
A high current density YBa{sub 2}Cu{sub 3}O{sub 7{minus}x} (YBCO) superconducting thick film on a flexible NiCr alloy substrate tape with ZrO{sub 2} + 10%Y{sub 2}O{sub 3} (YSZ) as buffer layer was prepared by pulsed laser deposition (PLD). The buffer layer YSZ of thickness 0.3 {micro}m was formed on the NiCr alloy substrate tape of length 6.0 cm by ion-assisted pulsed laser deposition (ISPLD). The YBCO superconducting thick film with thickness 1.5 {micro}m was deposited on the YSZ/NiCr alloy substrate tape by a KrF Laser. The X-ray diffraction pattern indicates that the YBCO superconducting thick film is with strongly C-axis oriented. The critical current densities versus temperature and magnetic film is with strongly C-axis oriented. The critical current densities versus temperature and magnetic field were measured by standard four-point probe method, the values of critical current density and the critical temperature of the YBCO/YSZ/NiCr alloy superconducting tape are 8.75 {times} 10{sup 4} A/cm{sup 2} (at 77 K, 0 T) and 88.7 K, respectively.
