Research Abstract

The condensation energy density of Bi-2223 superconductor, which determined the property of the critical current, was measured and the possibility of superconductor was discussed. It was found that Bi-2223 superconductor had potential equal to the practical rare earth-123 superconductor at low temperatures. In addition, the superconducting magnet working at liquid nitrogen was fabricated and magnetic field of 1.3T was successfully generated.
