Abstract: The magnetization curves of EuBa2Cu3Oy crystal prepared by melt-textured growth method were measured from 1.5 to 87K up to field 7.5T for H || C and H ⊥ C. Peak effects were observed at 60, 70 and 73K for H || C, and 70, 73 and 77K for H ⊥ C. It is shown that the magnetic field Hp at which the magnetization or critical current reach their extremum is approximately independent of temperature lire and the peak erects observed can be explained by matching effects.
