RARE EARTH SYSTEM TAPE-SHAPE OXIDE SUPERCONDUCTOR AND COMPOSITE SUBSTRATE USED FOR IT |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To form a second interlayer and a YBCO superconductive layer with excellent characteristics on a first interlayer excellent in surface smoothness on a substrate. <P>SOLUTION: On the surface of a biaxially-oriented Ni-W alloy tape-shape substrate 1, a second interlayer 2 made of A<SB>2</SB>Zr<SB>2</SB>O<SB>7</SB>with surface smoothness formed into a film of 5 nm or less through repeated coating and calcination for several times in an MOD method, a second interlayer 3 made of a CeO<SB>2</SB>film formed by a pulse deposition method, and film-forms a YBCO superconductive layer 4 formed by the MOD method and an Ag stabilized layer 5 on the YBCO superconductive layer to manufacture the YBCO superconductor 10 having a critical current density Jc of 1 MA/cm<SP>2</SP>or more. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
