FY 1998 report on the results of the research and development of fundamental technologies for superconductor applications; 1998 nendo chodendo oyo kiban gijutsu kenkyukaihatsu seika hokokusho. Chodendo oyo kiban gijutsu keknyu kaihatsu

Abstract

As to the research on the superconductor manifestation mechanism, Y123 monocrystal which was partially replaced with Zn and Ni was manufactured, and it was made clear that the addition of these impurities greatly change anisotropy of superconductors. It was made clear that instability of lattice and magnetism is included in high temperature superconductor. Also made clear was an important role in the Nb/Ba replacement in existence of magnetic flux melting phase transfer and the magnetic field induced pinning effect. The manufacture of Y123 bicrystal membrane was successful by the liquid phase epitaxy method. The manufacture of non-copper base K-Bi-O new superconductor was successful by the ultra-high pressure synthesis method. The stabilized process was established for large size crystals of 15-20mm square in Y base and of 20-25mm square in Nd base. Also successful was the growth by LPE method of crystal with thick membrane of 20mm x 20mm x 10{mu}m on the MgO monocrystal substrate. The non-bicrystalization of Y base Nd base monocrystal was successful, and the peak phenomenon control in Jc-H was found out. By neutron irradiation, the acquisition magnetic field of 3.7T at 77K was achieved using bulk Y base 123 material with diameter of 3cm. And, the  More>>
