粉状においてAgコートしたBi系バルクの超電導特性

抄録

Ag coated powders of oxide superconductor Bisystem prepared by the solid phase reaction method were sintered after pressing. The electrical resistance versus temperature, the critical current density, X-ray diffraction and SEM images were measured on these materials. Although the resultant critical current density is increased, the electrical resistance versus temperature characteristic changed slightly with the amount of sputtered Ag coat.
