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 ...

Effect of Ag addition on Unidirectional Solidification Processing of YBCO Superconducting Oxides
Zone melting/unidirectional solidification process from the partial molten state has been utilized to fabricate textured Y(123) superconducting wires with silver additive. The melting temperature determined fr...

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...
