Abstract

A magnetization study using three techniques with different time scales down to 10^-4 s has been performed on single crystals of the three-dimensional high-T_c superconductor Ba_0.6K_0.4BiO₃. A fishtail effect (second peak in M(B)) is observed in a large temperature range down to the shortest time scale. At high temperature (T = 0.74 T_c) the peak is still visible for the shortest time scale but disappears with increasing waiting time showing that it is not related to flux creep phenomena. The origin of the fishtail effect in high-T_c superconductors is discussed.
