摘要：

Magnetic measurements have been performed on a melt-textured grown (MTG) GdBa2Cu3O6+y, sample. Because of the paramagnetism of the Gd3+ ions, the magnetization relaxation rate is increased by a factor of 4 pi chi. The effect of paramagnetism on the U(J) relationship of the sample has also been discussed. At the end, we extraxted the U(J) relationship based on the field sweep rate H, which is in agreement with the one after corrections for paramagnetism.
