specific Embodiment 1
[0032] The YBCO superconducting layer is prepared by laser method, the target material is YBCO target of Φ50×5mm, and the base distance of the target is about 40mm. The target is kept spinning during deposition.
[0033] will carry CeO 2 / YSZ / Y 2 o 3 The NiW metal substrate of the isolation layer is pasted under the stainless steel leader tape, the size of the substrate is 5×10mm, and the sample is placed above the target.
[0034] Close the cavity of the vacuum equipment, and evacuate to 2.5×10 -4 Pa, the substrate temperature is heated to 750°C, and the temperature is read by a built-in thermocouple (715°C measured by an infrared thermometer). After the temperature is stabilized, oxygen is introduced into the cavity to control the oxygen pressure to 20Pa.
[0035] Turn on the laser, select frequency 10Hz, energy density 1.8J / cm 2 , deposit YBCO film on the substrate. Afterwards, increase the temperature of the metal baseband by 10°C at the original temperature and keep...
