摘要：

Isothermal DC magnetization in fields up to 5 T and harmonic component (AC fields of 1.1 mT) data for a sintered Tl2Ba2Ca2Cu3Ox powder sample are reported. The sample contains mainly the 2223 phase, with a diamagnetic onset at 115 +/- 1 K. The initial magnetization curves at various temperatures scale to a single curve. This behavior and the results of the harmonic analysis agree with general predictions derived from critical state current models.
