Kurzfassung:
We have fabricated the bulk Y–Ba–Cu oxide, various types of wire conductors and coils, and especially studied the critical current density J c . Large J c 's were obtained at 77K and OT: 725A/cm 2 for the non sheath wire, 560A/cm 2 for the Ag sheathed wire. However, the J c (77K) drastically decreased by a factor of hundred in a magnetic field lower than 1T while J c (4.2K) little changed up to 12T. Based on the magnetic field dependence of J c , for example, 2T of upper critical field Bc2(77K) and 47 to 80T of Bc2(4.2K) were obtained for the wire conductor.
