Abstract The magnetization curves of EuBa₂Cu₃O_y 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 H_p 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.
