    Microstructual Control of Bi-System Superconductor Prepared by Partially Melting Process

    The uniaxial pressing method in a partially molten state for Bi-system superconductors has been attempted in order to realize the high Jc materials. To prepare the Bi-2223 powders, we proposed a new technique ...

    The melting and solidification mechanism of R123 high Tc superconductor (R=Y,Sm,Nd•••)

    The improvement of critical current density(Jc) of REBa2Cu3Ox (R=Y,Sm,Nd•••, R123 hereafter) has been performed by means of unidirectional melting and solidification. The high temperature stable phase crystals (Y...

    Effect of Undercooling on Solidification in YBCO

    Y1Ba2Cu3O7-δ (Y123) crystals were grown by the undercooling method at constant temperatures with Sm123 seed crystals in order to investigate a relationship between undercooling (ΔT) and a growth rate (R). The cry...

    Flux Properties in YBa2Cu3O7−δ and Inhomogeneous ESR Broadening

    Inhomogeneous ESR broadening due to local field distribution was observed in the mixed state of YBa2Cu3O7−δ with Tc = 91 K. The change in the ESR lineshape was investigated with paramagnetic “spin probes” applied...
