摘要：
We report on very high trapped fields (13.3 T at 33 K) achieved in bulk YBa2Cu3O7-delta melt-textured monoliths, which were reinforced by steel tubes to compensate the tensile stress generated during activation. The flux pinning properties were improved by neutron irradiation. The resulting increase of the critical current density shifts the maximum attainable trapped fields to higher temperatures (by about 10 K). (C) 2002 American Institute of Physics.
