Superconductor and precursor therefor, their preparation and use of superconductor
摘要：
A superconductor comprising a compound of the formula (II): R 1+x B a 2-x C u 3 O 7-y1 wherein not less than 40% of a crystal of the superconductor shows phase separation, and at (temperature, magnetic field) of (77[K], 0[T]) and (77[K], 4[T]), a critical current density is not less than 10,000 A/cm 2 , which is obtained by heating a precursor which is a solid solution of the formula (I): R 1+x B a 2-x C u 3 O 7-y wherein not more than 10% of a crystal of the solid solution shows phase separation, so that phase separation is formed in the crystals at a phase separation temperature, and introducing oxygen.
According to the method of the present invention, a superconductor having a high Jc
which is unobtainable by the conventional production method, can be obtained using the conventional materials.
摘要（中）：

包含式（II）化合物的超导体：其中不少于40％的超导体的晶体显示出相分离 和（77ÄKÜ，0ÄTÜ）和（77ÄKÜ，4ÄTÜ）的（温度，磁场），临界电流密度不小于10,000A / cm 2，这是通过加热作为固溶体的前体 式（I）的化合物：其中不超过10％的固溶体的晶体显示相分离，使得相 在相分离温度下在晶体中形成分离，并引入氧气。 根据本发明的方法，可以使用常规材料获得具有通过常规生产方法无法获得的高Jc的超导体。
